Do safety warnings count?
If so, the warning on bags of balloons that tells you not to blow balloons up by mouth.

Unfortunately, I can't get on right now. Gotta go to bed soon. I have a shitload of things to do starting in like... 6 hours. -__-
Eh, most balloons that are marketed as being penis shaped don't really look like a proper dick.
Though you can totally make a dick with one of those twisting balloons that are used to make balloon animals.
