Who ever invented Band Aids, was a jerk. That is my conclusion. Why?
Usually one puts a Band Aid over a cut (often a small pathetic cut thats not even worthy of a band Aid) or a narsty scar (Unless your trying to be all gangstar and put it on the side of your face..... ) .
You see band aids were meant to make you feel better and brag about whatever "warrior scars" you got. Well guess what band Aids DO NOT make you feel better. Ever try to rip one off ?
You rip off your band aid and you end up ripping off the scar and half your arm hair and skin. So now your bleeding all over the place and you disgusted yourself out with the whole scar being ripped off and the pain of ripping the band aid is stinging your arm like a bitch. And now half your arm hair is gone and you will look like a freak or a flinging fruit cake with a smooth spot on your arm. Reaaaal coool. See this is a prime example of why whoever invented the band aid is a jerk.
Now some people have different styles to rip off the band aid to avoid as much pain as possible. Personally I rip the band aid slowly This of course causes more pain. I cant rip it off fast. And if you did rip off fast it will still hurt. Or I put bunch of soap on the band aid, but again this will seep into the cut or scar and sting like a MF. So no matter what weird style you got for ripping a band aid off .... it will hurt.

Moral of the story bleed all over the place, you wont need a band aid.
