We really wish we had Jimmy Fallon's job sometimes.
The Tonight Show host and the ridiculously gorgeous model formed a human wheel during the telecast, which involved the stars latching on to each other's ankles and rolling around on a mat.
Fallon promised he wouldn't peek up his guest's dress, but then admitted that he couldn't resist the temptation.

Fallon also recently danced with Chris Christie.
