Warning signs are pretty important, right? This is especially true when they tell us when something's dangerous or harmful. Obvious stuff. But sometimes law enforcement (or regular folk) go the extra mile and choose to warn people of more-important-than-normal circumstances, like not drinking the toilet water or refraining from licking walls.

Trust us-- these cautionary signs are a vital part of our society, and without them, we'd be riding the buffalo... or something. Just kidding-- there's no way we can take these warnings seriously, but that's the best part! Check out 11 of our favorites.
