A Look at "The Comic Thread" - Funny People You Should Know

It's hard to be funny these days. The Comic Thread is a comedy troupe near Chicago that manages to keep doing it despite controversy.

Actually, I didn't mind. I was just glad to be there. I had, over the months, gotten to know one of the key figures behind this troupe, Nicolas DeGrazia. He had invited me after what had been a very contentious and strenuous couple of months for The Comic Thread.

The group first came into existence in 1998. One of their first performances was an arts festival that Highland Park holds every year known as FOCUS. So far, every time I try to explain FOCUS, I manage to get it wrong. So, really, all you need to know is that it's an arts festival where performers and artists and writers and people in the arts community come and do their thing and somehow it all involves the high school. If you live in Highland Park, you can probably connect the dots better than I.

Anyway, The Comic Thread has been a part of FOCUS since 1998. However, this year, their invitation was rescinded. Why? Because they may have offended the Amish.

One of their classic bits was known as "Great Moments in Amish Pornography." The bit worked by having the stage be dark. An announcer states "And now another Great Moment in Amish Pornography." The lights go up to the strains of the 2001 theme. A man and a woman stand on the stage dressed in Amish gear. As the music continues the girl raises her skirt up over her ankle. Meanwhile, the guy lowers the straps of his suspenders. Notice I said "straps" of his suspenders. I once wrote about this and got angry letters asking me why I thought a man taking his pants down wasn't porn. No, he does NOT lower his pants, he just lowers the straps of his suspenders.

Well, the FOCUS people first objected to the use of the word "pornography" in the title. The members of TCT agreed to change the title to "Great Moments in Amish Reproduction." They were then told this might be offensive to the Amish. Yes, they were told it might be offensive to the Amish. For those of you who are slow, let me say again, they were told it might be offensive to the Amish.

First, there are NO Amish anywhere near Highland Park. As far as I could tell, the FOCUS people had no plans to ship Amish people to the festival from Pennsylvania or Indiana or whatever. Finally, if the Amish did hear about it, so what? They're Amish. What are they going to do? Are they going to take their horses and buggies and plowshares to the big city to protest?

Anyway, The Comic Thread, much to their disappointment, found themselves dis-invited. However, they have managed to take that moment of disappointment and turn it into one helluva show which they performed at the Apple Tree Theatre this weekend. These are very funny people and they should be encouraged as much as possible.

The Theatre is wonderfully small and set in a kind of round so that the audience is all around the performers. If you sit in the front row, as I have, you are pretty much on stage. The show opens with an introduction by a man in a banana suit. Already this is something you have to enjoy. Oh, and he plays the trombone.

Nic DeGrazia manages to throw on costumes and bring a number of voices throughout the performance. He is also one of the writers and the director of this production. His interpretation, during a skit about "Avant Garde" theater, of a bowl of rice about left me gasping for breath. He can also, evidently, scream like a girl if needed.

He has managed to surround himself with equally talented and funny people. It's hard to be funny. It's hard to write funny. It's especially hard to write funny when everyone in the world is trying so hard to be politically correct and not hurt anyone's feelings, including the Amish. These guys manage to do it and do it well.

Elisa Redish is a spritely little thing who manages to portray a number of characters throughout the production. One of the funniest is a look at the Peter Pan story through modern eyes. The fact that Peter is usually played by a woman on the stage production is finally addressed. Little is done to conceal the fact that Redish is very female and the result is very funny.

Charles Turck also manages to portray a wide variety of characters. His touches to the role of one of the younger Darling children during the "Peter Pan" sketch are hilarious. One of his key humor moment is to leave the back of his pajamas down when he gets up and runs across the stage. He also plays a man who doesn't really know what "bronchitis" is toward the end of the show.

Ashley Neal is the second female cast member. She manages to be the cerebral center of the entire troupe during the "Avant Garde" sketch. At the same time she also can tilt her head to the side and portray a complete psychopath. I haven't met her, so she may be a complete psychopath which, if that is the case, then maybe she isn't that great of an actress, however, I don't think that's the case.

Finally comes one of the newest additions to the cast, Brian Quijada. Other than horribly misspelling his first name, his bodily contortions throughout the production kept the audience in stitches. He manages to go from playing a man running a short foot race in slow motion to a ferry captain on par with the sea captain from "The Simpsons." He's very funny, in short.

The entire production is hilarious. The skits are well produced. Heck, I even admire how the cast is able to get around and arrange the stage in total darkness. They manage to be edgy and funny and that is much needed in this day and age.

In a time when being funny likely means getting sued or ending up with self-righteous nincompoops like Al Sharpton protesting you outside, it's a tough business to be in. The Comic Thread manages to do it without always going for the lowest-common-denominator in each sketch.

I don't know when they will be performing again, but I hope it's soon. If they need a ticket-taker, they can call me. I also don't know if you can hire this group for something you may be planning, but you can check them out at www.bitterjester.com/tct. I will now end this article, review, description about The Comic Thread that only those at the show or those within the troupe will get. Still, I think it best sums up the experience of seeing this group of funny people in action.
