Jay Leno knew exactly what a Jersey Turnpike was when he asked Deena Cortese about it on 'The Tonight Show' (Weeknights, 11:35PM ET on NBC). He just wanted to hear the 'Jersey Shore' cast member explain the dance move.
When she stumbled around to find the words, he suggested she just go ahead and show him. Luckily for him -- or not, depending on your perspective -- Ed Helms was the first guest, and he was still on the couch, so Deena invited him to dance with her.
The move required very little from him. He simply stood there, while she backed up into him and shook her butt. "That's a Jersey Turnpike?" Helms marveled when it was over. "I had another name for that."
