September 17, 1980. Memorial Stadium, Baltimore. Tigers batting in the top of the first. Rick Peters grounds out pitcher-to-first and Alan Trammell singles to right. With Al Cowens at the plate, first base umpire Bill Haller calls a balk on Orioles starter Mike Flanagan. Orioles manager Earl Weaver does not agree.
Weaver's tirade may or may not be legendary, but Haller wins the argument. (Here's a longer, clearer version, with Eddie Murray talking to Haller before Weaver arrives.)
Weaver: That's bullshit!
Haller: ... behind the rubber.
Weaver: Ah, bullshit!
