Actually, funny story, this happened to me at work. We have a required set of rules for passwords: 8 characters long, have to have numbers and lettters, etc.
This guy said he wanted: bigc*ck
I could hear a coworker in the back sigh as he said it. Ultimately, I had to tell him that it wasn't long enough. Well, they had me on speakerphone, and she fell out laughing.
Good times
Edit - wow, just realized how bad that was. Reworded to sound a little more like english
