Paul Pierce isn't a 1-time flatulence offender -- the dude farts on his coworkers all the time ... so says Jalen Rose.
Of course, Rose was in the room when Paul let one rip right on Michelle Beadle this week during a taping of ESPN's "Off The Clock." In fact, it was Jalen who called Paul out on the air.
Another great — or perhaps disturbing — moment from this episode.... Paul may or may not have farted at the start of the taping: pic.
