At work we have some of those high pressure cans of air that you use to blow the dust out of your computer. You know the kind with the long red, thin tube you stick in it? I was looking at it the other day and there’s a drawing with a big red slash through it of a guy sticking said tube (attached to the can of air) in his ear. It says WARNING! DO NOT USE IN EAR CANAL. MAY CAUSE SEVERE DAMAGE.

Well, duh.
