Prank war gone too far?

As a bit of a jokester myself, I enjoy watching or hearing funny bits. I was watching VH1's 40 greatest pranks countdown the other day on television and a spot came up that had me speechless. I didn't know whether to laugh or take pity. The prank came from collegehumor.com. Two friends were having a prank war back and forth when one may have taken a joke a little far.

You be the judge.
