instead, because i didn't turn and it hit me in the back of my head, i've become strangely repetitive

From ESPN.com:

Clemson coach Tommy Bowden said Friday he was hit in the back of the head with a mini glass liquor bottle while standing on the sideline during Thursday night's 24-7 loss to Virginia Tech at Lane Stadium. [...]

"Had I turned and had it hit me in the eye, it would have killed me," Bowden said. "It was glass. That's what scared me. Those plastic ones, it wouldn't go that far."

Bowden said he gave the bottle to Clemson athletic director Terry Don Phillips, who was standing on the sideline. Bowden said officials made an announcement warning fans not to throw objects on the field.

"I really was afraid after that because had I turned and been hit in the eye, I surely would have lost the eye," Bowden said.

In any case, even though college football coaches get paid roughly two orders of magnitude more than college professors, at least we don't have people throwing glass bottles at us while we are doing our job.
