Bill’s Are Off Limits
There are so many different types of names in this world. And considering there are also so many different words as well, some names and words are bound to get mixed up. And when it happens, there are bountiful jokes to be made.

This sign quite obviously is not referencing people named Bill, but because Bill is a common name, someone decided to pull this very funny prank. Honestly, if something says prohibited, people are much more likely to do the thing they are not allowed to do.
