Denver Broncos quarterback Tim Tebow looks like Friar Tuck after he got the world's worst haircut as part of a training camp stunt pulled on rookies (full photo below).

Tebow and the other rookies had their heads decorated with wacky haircuts before the workout and they had to show them off during warm-ups when they couldn't hide underneath their helmets.

"I think all the rookies had a good time with it," Tebow said. "It was something to give everybody a laugh, something also to build chemistry."

Tebow has been a huge hit in Denver, with his limited edition shoes selling out in five minutes. However, don't expect a lot of imitators for that haircut.
