I've always been a little leery of t-shirt canons, even from long distance. I've said it before, it's not that I don't trust my abilities catching an item shot out of a novelty canon, I just don't trust the person in front of me who's gonna have it tip of their fingers right into my eyeball.
Anyways, this is another kind of problem with the canon. Chip the bull, the mascot of the University of Colorado buffalo's had an accident the other day and it included pointing the t-shirt canon the wrong way and shooting himself right where it counts.
Check it out on the video below...
Chip was then carted off the field to get his buffalo parts assessed in the training room...
