In this clip, which rose to fame in 2007, Mississippi Braves manager Phillip Wellman (of the Southern League) throws a tantrum that would impress any two year old.
Wikipedia gives the blow-by-blow:
He protested the umpire throwing his pitcher out of the game for using a foreign substance by covering home plate with dirt, then tracing in the dirt a new, significantly larger home plate. He then went on to uproot bases and throw them, crawl in a prone position across the infield like a soldier, and pretend to bite and hurl the rosin bag at an umpire as if it were a hand grenade. He concluded his tirade by pretending to eject the umpires themselves with a fist-pump and then blowing a farewell kiss to the crowd while taking a bow.
