I just saw a post about "Funny signs" and remembered a really humorous site where you can create your own funny street, building, highway and other signs with your own dialogue.
Currently there is a Bar-Be-Que Restaurant sign but you can scroll down and see more for your posting pleasure. I have used the sight many tomes to create funny or sarcastic signs for friends and clients and then send it to them by email. At first look it appears like you have taken a picure of a real sign and it always gets a reaction.
Try it and I guarantee you will laugh (and probably waste some time creating your own signs!
Enjoy! Now I have to get back to work!
