Insane Disclaimer in the Monsters Inc. Laugh Floor ride in the Magic Kingdom
Ah, lawyers!
This insanity is actually part of the show, on a giant sign in the queue for the Monsters Inc Laugh Floor. It's part of their Living Character Initiative, where CGI characters voiced and choreographed by backstage performers interact with guests in the audience, and there are several signs in the queue asking you to text message in jokes to be used during portions of the show.
Apparently the telling of a joke requires a giant disclaimer among all the whimsical signage that's supposed to convince you that you've crossed over into Monstropolis. This particular sign is the most egregious example of the real world ruining the fantastical, as it's the largest sign in the place soliciting jokes and half of it is used up by this disclaimer.
This did not stop me from submiting the following, lifted from The Garry Shandling Show:
When does a policeman stink?
When he's on duty!
They didn't use it.
