Last time I was in
San Francisco I noticed one such sign in a
parking garage, where they have those mechanically raising bars at the exit. They show a picture of
Mr. Ped having the bar dropped on his head, where it breaks and has him
seeing stars.
While that one's a little amusing even, with the stars floating about his head, I noticed some darker ones on some of the beaches on Maui:
- no diving: Mr. Ped is shown diving into water 1-foot deep. He's just about to accordion half the length of his body into a huge rock.
- shorebreak: Mr. Ped has taken up bodysurfing, and is riding a 10-foot wave about to crash straight onto the beach with no water below
- Man-O-War: Mr Ped's leg is being stung as he's surrounded on all sides by jellyfish half his size.
