Jimmy Fallon's games of 'Catchphrase' are usually pretty madcap when he has your average celeb on to play, but bring Triumph the Insult Comic Dog into the mix and all hell breaks loose.

It's also far funnier, only because Triumph gives zero f*cks.

This is like whenever Dustin the Turkey would show up on The Late Late Toy Show and you just didn't know what would happen or come out of his mouth next but that made it all the more entertaining. Poor Colin Firth is just lost in it all.
