I did not find this one myself. I do not see a grammatical mistake, but I think this is super funny. 

There is no method to the madness of capitalization in this ad. "Worlds" should be "world's." Perhaps it should be "If you are the world's most famous" or "If you are a world's famous." This just does not work. 

Thanks again to Amber! I will repeat Amber's question to me: How many kids can you eat? he he he 

There were two of these signs with the same mispelling. "Agressive" should be written "aggressive." I found this sign at the Little Rock Zoo.
The chimpanzees were not exciting at all, but the gorillas were beating their chests and fist fighting. All of the males in our group were quite impressed. Only I was impressed with finding a sign containing a mistake.

Thanks, Amber, for your careful attention to the incorrect/unnecessary use of the apostrophe. Apostrophes do not make plurals.
Upon revisiting this blog entry, I realized that there is another error in this sign. Prepay before pumping is redundant. It should be "pay before pumping" or simply "prepay. "

Thanks to Dad for this one, too. This one can be found in Augusta, Arkansas. I think they are selling TRAILERS not TRAILORS. 

This sign in Searcy, Arkansas, has annoyed me for some time. Thanks to my dad for capturing this one. In case you are wondering, the sign should read, "YOU'RE HERE NOW."
