This was a great coaching episode about a complexing and potentially polarizing challenge. I am totally onboard with Matt being wary of meta-sketches, but at the same time you can't just dismiss a sketch because it is meta. Just like any sketch, there is a right and a wrong way to do a meta sketch. Funny is funny.
That being said, I feel any meta-sketches may have a failure rate much higher than other sketches (absurd, topical, etc).
And a general question:
Mr. Show's opening sketches had Bob and David playing themselves every time, whether David wound up in a dress then ultimately portrayed by Sarah Silverman, or Bob becoming a cult leader and exclaiming 'TARA-DE-LOO!' Are those considered meta because Bob and David are playing themselves? Is the Colbert Report considered meta because he is playing himself?
I am anxiously awaiting to see what the contestants come up with for this challenge.
