Wee baby Cumberbatch is barely a year old and his dad's already got embarrassing wedding dancing down pat.

Cumberbatch is hosting 'Saturday Night Live' this weekend and stopped by Jimmy Fallon for some advice and some dancing to warm up for the event.

He also took part in a game of 'Mad Libs Theater' but we won't subject you to that torture here because while Cumberbatch is good at coming up with his words, the follow through is just painful.
