I watched the two-hour finale, and weirdly, the least funny comic of the final five, Felipe Esparza, won the $250,000. I meet the news with a shurg because previous winners haven't really gone on to anything.
The thing that stuck out most to me was when Kathy Griffin performed. She had pumped-in laughs. Everyone else who performed had to earn the laughs of the crowd, but every punchline of hers got the same amount of laughs at the same volume. It was weird.
