There used to be a firm of oral surgeons in my hometown (the ONLY oral surgeons for about 200 miles around so it wasn't like you had a choice) called Slaughter & Savage.
I saw a sign on a café in Paris stating, in big pink neon letters, FRENCH FOOD. Well, thanks for telling us!
There are lots of signs in the hills where I grew up saying Wildfire Evacuation Route and pointing in the appropriate direction, but my friend Caitlin once misread it and said, "Why do we need a Wildlife Evacuation Route? Can't they get out on their own?"
On a chalkboard menu outside another French café of the type that sells crepes, ice cream and drinks, I saw the advertisement "Poissons Frais" (Fresh Fish). I assume some wag erased the bottom bit of the B and it was meant to be "Boissons Frais" (Cold Drinks). But it made me giggle.
