1. People who just can't get by without slamming a rock star... or red bull... or 5 hour energy shots. How about a good nights rest and some fresh air perhaps?
2. Professional body builders... male or female. Is this guy happy or ticked? I can't tell, but I sure wouldn't want a roundhouse kick to the face from him. No worries, I don't think he could get his leg up that high anyway.
3. Bullfighting. The picture I saw this morning was a guy with a horn through the face... I censored and found this one of a close call, but you can imagine that sometimes the bull doesn't miss. Yikes.
4. White people with dreadlocks. Common man, Jamaican me crazy with that hairdo...
5. Colored Ketchup, which I think they discontinued, but I still have disturbing mental images of purple goo on a hot dog.
