Probably a technical glitch. The forum software has been acting up lately, and the signature database system has been mixing up parts of one user's signature to another's. It's rare, but that might have been the case. I don't think any of our moderators, myself included, would put something like that into your signature. We're very serious people.
And if we were to find out such a thing that a moderator put it in your signature it will be grounds for instant dismissal of duties.
