Things got a little heated at the UFC 156 press conference today when Alistair Overeem and Antonio "Bigfoot" Silva walked in for the stare down.

Aldo, Edgar, Evans and Nogueira all remained both professional and respectful, but the heavyweights on the other hand. All I can say that the words "You better start showing respect" were replied to with a simple "I'm going to F***ing destroy you".

Watch for yourself.
