A College Mascot Shot Itself in the Groin with a T-Shirt Cannon

The mascot for the University of Colorado-Boulder got carted off the field at a football game last weekend . . . after shooting himself in the groin with a T-SHIRT CANNON.  He tweeted later on that he was okay though.

It's hard to tell, but it doesn't look like he actually got hit with a shirt.  It looks more like the cannon just backfired.  But at point-blank range, even a shot of compressed air could do some damage.

Here's video of him being carted off the field
