These are from a book i was bought a few years back called, funnily enough, "the worlds stupidest signs"
1 - "If you cannot read this, this leaflet will tell you how to get lessons"...
2 - "do not turn upside down" printed on the bottom! of a tiramisu dessert box........
3 - On a korean kitchen knife "please keep out of children"...
4 - "elephants please stay in your car"
5 - in a factory "would the person who took the step ladder yesterday please bring it back or further steps will be taken"
6 - on a luggage trolly at singapore airport! "not to be removed from crewe station"
7 - on a repair shop door "we can repair anything - please knock hard on the door, the bell doesnt work"
8 - in an american maternity ward "no children allowed" (youd be a bit peed off wouldnt you?)
9 - "Same day dry cleaning, all garments ready in 48 hours"
10 - "This product not tested on animals" on a new-zealand insect spray!!
Some of the best for you!
