Longest game?

Played a 21 inning game last night. I can't remember a longer one. Anyone play more than 21 innings?

21 is the longest I've heared of. That would be another good stat to keep track of. In "Record Book 2011"

I think I've gone in the 24-27 inning range a few times(of course, I've played like 100,000 games). I distinctly remember the first time, as one of my relievers almost threw a no-hitter in extra innings, throwing 8+ innings of no-hit baseball.
