You'll be charmed by this great prank from the Prangstgrup, where a student goes all jazz hands on his professor and peers. We're not sure of much else about when or where this performance took place, but we're betting on a small, possibly Ivy, institution. At the big ole land grant college we went to, this kid wouldn't have lasted long before a roughneck classmate had had enough. (Thanks to Brad for the tip!)
UPDATE: It is an Ivy; you brainy letter-writers out there confirm it's Columbia University, and the charmingly bemused professor is one James Valentini, in the chemistry department.
