I actually loved it, couldn't keep from giggling throughout the whole thing. I'm sure he did the corny jokes and the reading off notecards as a purposeful gag, sort of an Andy Kaufmanesque bad comic routine. And I love the technique where he tells a lame joke, and then explains the obvious punchline in so much detail that I can't keep a straight face. "Bob has lots of well-wishers here; they want to push you in a well! [Pause]. They want to murder you by pushing you in a well. [Pause]. Seems kind of harsh, but apparently they want to murder you in a well, it says on this card."
Norm MacDonald, Jim Norton and Gilbert Gottfried were the best part of the roast of Bob Saget. Norm and Gilbert have this underlying sensiblity or something that makes them geniuses. They can have very smart material and be hilarious, or have crappy material but still be funny with it.
Gilbert is very underrated.
