Apparently there was a running joke on the set of Inglourious Basterds, whereby if a crew or castmember was caught sleeping, they would get their picture taken with a giant purple dildo, and that giant purple dildo was named Gerry:

Nice to know no matter how successful, famous, or creative you are, dildo humor never gets old.
