A University senior named SHAINA made one of those ambush-style YouTube videos asking Taylor Swift's ex, JOE JONAS to her formal. And it's actually pretty funny.

Joe couldn't make the dance, but he did make a funny counter-video, offering to fly Shaina to a concert in Chicago.  In the video, he's wearing a Wonder Bread NASCAR racing suit, kind of like WILL FERRELL'S outfit in 'Talladega Nights: The Ballad of Ricky Bobby.' And he's lying on his side and sipping wine.

It's set to an instrumental version of WHAM'S 'Careless Whisper' and even includes a cameo by that YouTube SAXOPHONE SUPERSTAR who goes around playing it in public.

Yesterday, Shaina was on the 'Today' show to talk about all this chaos, and Joe surprised her by showing up in a wig and fake nose and mustache. She still recognized him before they could even introduce him. She was freaked at first, but she recovered quickly enough to crack a joke.
