I hate to see people smoking in a car with young children in the back seat with the windows rolled up (or just slightly cracked). Actually, children of any age. It's child abuse and should be treated as such.
*stepping off my soap box*
People who say "oh I can't run/not eat sugar/lose weight/eat better" when what they really mean is "I don't want to".
Commercials that make all men look totally stupid and helpless and all women look like disgusting pigs who have every "female" problem known to man.
Done. (For now). LOL
