On Friday, everyone across Wall Street was absolutely transfixed when hedge fund titans Bill Ackman and Carl Icahn, who have been notoriously feuding for a decade now, went head-to-head on CNBC's "Halftime Report."

The insults were flying with Icahn calling Ackman a "crybaby in the schoolyard" and dropping curse words left and right. Ackman, who refrained from using profanity, mostly called Icahn dishonest and not a nice person.

Of course, Icahn and Ackman aren't the first to fight on Wall Street.
