"I think lawyers are talking right now," Critch told CBC's St. John's Morning Show on Wednesday.
"You can't do that. I mean people have ripped people off before, millions of times, but this is word for word and DHX Media — which owns own 22 Minutes — said they want to protect their intellectual property."
The sketch in question involved a Win, Lose or Draw-style show where contestants were asked to draw the Muslim Prophet Muhammad — a blasphemous act according to mainstream Islamic tradition.- SNL's Prophet Muhammad sketch is a lot like old 22 Minutes joke
Critch, who writes and performs on 22 Minutes and who appeared in January's sketch, said that while the different comedy groups will often cover similar ideas, this case is different.
"They did pretty much the exact same sketch," he said.
"Never ever, in all my years of of making fun of people, have I seen anything that's pretty much word for word," he said.
"It's kind of like if two different high schools are doing the same production of a high school play, different actors but the same thing."
Possibly a writer looking to get noticed
Critch, who has first-hand experience on how the process of a comedy show works, thinks he may have an idea of how SNL came to do the same sketch.
He said shows like SNL and 22 Minutes will have often have "pitch meetings" where writers submit ideas for the show, and that someone may have been desperate to get their idea considered.
"Sometimes it can be a lot of pressure, especially in something like Saturday Night Live," he said. "Maybe someone hasn't had something on for a couple of weeks, so they start to panic a little bit."
He speculated that someone may have gone looking online for ideas to pitch to the producers.
"Just to get something read at the table read is enough to keep you on for a few weeks sometimes," he said. "Maybe somebody had a look, found this, and thought 'OK, I'll pitch that.' "
2nd recent accusation of plagiarism against SNL
This isn't the first time this season that SNL has been accused of using someone else's intellectual property. In October, Los Angeles-based group The Groundlings publicly spoke out after a skit was aired on SNL that bore an uncanny resemblance to one of their own.
The sketch, which involved three backup dancers dressed up as Tina Turner singing Proud Mary. In both instances, the performers were wearing similar dresses, wigs and were even singing the same song. SNL later removed their version of the skit from syndication and the NBC website.
Critch said that example, like the 22 Minutes sketch, shows a troubling pattern with the writing at SNL.
"I think something's on the go over there," he said.
"Somebody's a bit desperate."
