Ok, so I am at the Crown Plaza in Philly, and I notice a sign on the 18th floor:

This is a quiet floor.
There will be no housekeeping between the hours of 9pm-10am.
Liesure travelers, marching bands and circus animals will not be placed on this floor.
If you are staying on this floor, please help us keep quiet by:
Keeping your TV on a Low volume &
No loud singing in the shower.

I do plan on taking a picture of this sign later. I took my fellow travelers to see the sign and we ended up on the floor laughing (probably laughing a little to loud). This sign probably goes unnoticied by many.

Anyone alse notice amusing signs while out and about?
