Saw him at a small club in Denver in 1999. I still think that is the funniest show I have ever seen live. Followed him closely until he killed himself — a damn shame.
That got me thinking of what the funniest show I've seen live was. And I think the one I laughed hardest at was Rich Hall, who I saw at the Edinburgh Fringe Festival in '96 (and everyone should experience this at least once). I think part of it was the setting, the fact that I'd seen several UK comics and didn't get all the references (and sometimes couldn't decipher Scottish and Irish accents), so I was looking forward to a US comic. But Hall might be the quickest on his feet of any comic I've seen, and there have been many. He rarely tours the US, but he's huge in the UK and Australia.
Btw, have to ask if Johnny Rizzo is still working the clubs in CT. Back in the 80s it seemed he opened for everyone, including the worst show I ever saw, which was Dice at the Treehouse back in the 80s. After his opening nursery rhyme bit, he was truly awful. People were actually asking for Rizzo to come back on. Rizzo had a face for comedy and with all the love for Maniscalco on here, maybe it's finally his time, lol.
