Basically, just suggest completely crazy ideas for road signs completely and thoroughly ripped off from here
Attention: Story time ahead
Two absolutely true ones. Near my house is a stop sign, says STOP in big black letters.
Under it, someone has written HAMMER TIME.
At the top of the road I grew up on is, unusually for the Isle of Man, a hill. At the top of the hill is a 19th century village called Cregneish which, no lie, a friend of mine was once paid to live in as part of a living history project.
At the bottom of the road to the village, there are two signs. One says
CREGNEISH HERITAGE VILLAGE
the other says
CREGNEASH HERITAGE VILLAGE
