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.
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.
The video was referenced again in Season 21, this time with the addition of Sasha Farber imitating Bruno in the video.
Honestly, pretty much anything that comes out of Tom's mouth that isn't in the script. The man is hysterical.
For starters, Tommy Chong dancing cha cha to Snoop Dogg's "Drop It Like It's Hot". Complete with his partner Peta Murgatroyd dressed as a weed. And surprisingly dropping it like it's hot! Bonus points for Cheech Marin pumping the lowrider in a Funny Background Event.
Even better when they did the dance again during the finale...with Len Goodman in the lowrider's driver's seat wearing a hip hop jacket and some bling.
Then he danced a surprisingly good salsa where at one point, he ripped his shirt off to reveal his man boobs! (when Erin pointed it out, he asked her, "Wanna touch my boobs?")
Tommy imploring America to vote for him and his partner, "because if you do, we'll save the world!"
Erin asked him if there were beautiful girls in jail (he was incarcerated back in 2003) and he told her, "NOT GIRLS!"
Then Erin asked him if he wanted to dance with Tony Dovolani during the switchup week and he answered "I'll take Tony... I've been in jail!"
When he was criticized (rather harshly) that he looked tired while dancing the mambo he responded, "well I look tired because I'M OLD!"
Him and his partner Peta's first meeting... on a smoke-filled van. Peta's reaction is priceless.
Tommy taking Peta to the desert for some "relaxation"... then he hallucinated Cloris Leachman was talking to him on the cloudless SKY-pe.
His airplane/Mile-High Club-themed trio samba with Peta and Sharna to Jason Derulo's "Talk Dirty". Since this is Tommy Chong we're talking about, the seats in the background were green, and before the dance, there was an announcement about "flying high on Chong Airlines". Right before receiving his scores, when he was asked how he felt, he said, "It was hard."
It's even funnier because after his other dance earlier that evening, the judges said he had "subtle elegance". Now watch as he throws that to the wind and replaces it with Dirty Old Man!
A blink-and-you'll-miss-it moment, but after Tommy got eliminated he went up to the judges' table to thank them; watch closely as he shook hands with Len Goodman: he's inviting Len Goodman for some pot session with him!
