Before he throws punches, he threw tables.

Dereck Chisora and Dillian Whyte will get into the ring to fight for the British heavyweight title this weekend, but the fireworks have already begun. The pair attended a press conference on Wednesday to promote the bout and had some nasty words for one another.

Words eventually led to actions, though, when Chisora picks up the table where he's sitting and hurls it at Whyte. Someone from Whyte's camp responds by throwing an unidentified item at Chisora before the two fighters are separated.

And you thought there was bad blood between Donald Trump and Hillary Clinton.

Chisora and Whyte join the long list of boxing's ugly press conferences. There's a rich history of these events getting out of control. Take a look at some of the more memorable ones below.
