We don't have very much on Youtube, unfortunately. This clip if from an APBT show we did a while back. Specifically, what you're seeing is an example of a tag out run. We didn't invent this, of course, but it's something we're known for.
Essentially, at some point in the show (usually around the middle- we avoid doing this near the top), if someone comes out with a character the others think they can have fun with in a tag out run, this is what we do. The idea is to take said character and place him/ her in increasingly strange/ inappropriate/ comical situations.
I don't remember why I did it, but apparently in this video I was doing a scene with Kyre (who sadly is no longer with APBT, though she is in Women with Class) and the choice I made was to be a character who was totally accommodating and would agree to whatever anyone wanted. Dan then decided to make it a tag out run. At the end of this video, Kyre does what we call an "edit" or a "wipe". That's how we signify the end of scenes (this is done when one thinks the scene has reached it's peak).
PS: When Chris comes out with the mirror thing, that's a callback. A callback is a reference to an event or character that occurred/ appeared earlier in the show. He and Kyre had done a scene where she was a psychologist (or something like that) and was trying to have him look into a mirror and see his "true self". The scene ended with him saying something like "I can see... me eyes... I think I have astigmatism".
