Call me immature, but I get a kick out of rearranged road signs. My personal favourite was a signboard advertising for people to join the Edmonton police force. Some clever vandal had rearranged the words to read:
"Don't join the Po Po"
Awesome!
Close to our house, there's a big construction site where they're building what I think is going to be a Superstore. Anyway, attached to the fence, there's a placard that says "Danger! Due To: ", and then a big white space where the crew is supposed to fill in what the danger is on the construction site. The one I saw says:
"Danger! Due To: ZOMBIES"
Love it! That one made me laugh out loud (or lol - I probably would have rofled if I was walking) - which made me feel a bit silly for laughing to myself in the van.
