The Producers
SPOILER ALERT, for those who care about such things.
I've been rewatching all the shows On Demand, and just caught the season finale for season 4, where Larry debuts in The Producers. That one was a little unusual because Larry actually finishes as a success in this one. It looks like he's going to blow his Broadway gig, but ends up pulling it off.
It still sort of makes him look like a schmuck, because it is revealed that Mel Brooks only hired him because he thought he would destroy the musical. Brooks had grown tired of putting it on apparently.
I was watching the episode, and I thought damn this one is kind of dragging on forever, I had forgotten when I started it that it was an hour episode. The pacing on it seemed a bit slower.
