Not even a dance, but Tom showing the "I'm Still Standing" music video and highlighting Bruno's prominent role in it. If you listen closely, you can hear Bruno calling Tom a bitch, which only makes it funnier.
Best of all, it was actually a surprise—they didn't tell him about it beforehand, and that look of shock is real.
Back in Season 10, Bruno actually mentions hanging out on a beach with Elton John when Kate Gosselin danced to that same song (he proclaims that she ruined the memory with the quality of her dancing). Bruno might have been better served if he'd kept his mouth shut.
Honestly, pretty much anything that comes out of Tom's mouth that isn't in the script. The man is hysterical.
