YMMV / The Complete Works of William Shakespeare (abridged)
The Danza: Actors will generally just use their own names for the show, as the original run did.
He Really Can Act: Adam spends most of the play carrying the Idiot Ball. Then, halfway through Act II, he gives a quiet, understated performance of the "What a Piece Of Work is Man" speech. Played right (as Adam himself does in the video), it's a showstopper.
Throw It In: Both subverted and played straight. The show's conceit is that these guys are making it up as they go, and much of the "spontaneity" is actually scripted. Then again, improvisation is encouraged, and there is a lot that can go wrong, so no two performances are ever quite the same.
Austin discourages it though when Adam and Reed try to bring a toy Godzilla into his segment about Troilus and Cressida.
