Bruce Willis gave Justin Timberlake a run for his money in the outrageous sketch department on last night's Saturday Night Live.

The guest host starred in a bit called Boy Dance Party with every one of the male SNLregulars taking part.

The guys decide they "sometimes like to dance with just us guys," and do they ever!

After telling his wife, he and his pals were going to watch  football game while she goes out with the girls, Willis and the boys let loose.
