Girl I barely know (one of my sisters friends, she added me) has put as her facebook status "what shall I do for my 16th birthday?". I'm resisting the temptation to post something to do with celebrating her legality. I probably would if I was her age and I knew her well (as a well meaning yet sleazy joke), but obviously, with the situation that exists, that would be very very creepy.
Also, I sometimes work inside a power station boiler 160ft in the air. I keep feeling compelled to jump for no reason.
These aren't the best examples I can think of, but they're the ones going through my head at the moment. Anyway, lets hear about all of your examples of this kind of thing.
