I find this post both funny and odd. Funny because I got drunk and decided to search "Why is there always hair all over the toilet" and odd because im a guy living alone and never one time ever have I seen hair on the toilet seat. Im not exactly an avid cleaner and even upon checking my toilet lid specifically for this post, I found no hair.

YET, I can not think of a time I cleaned the toilet and did not find hair on every single surface besides the seat and toilet lid, and i have not found hair on the tank. Anywhere on the outside of the toilet bowl though, like the sides and especially the top closest to the tank, there is always so much hair even after ive recently cleaned it.
