I'm not gone yet

I'm still working in my department despite my tendering my resignation five months in advance. People keep walking up to me and asking me why I was still there. Apparently someone sent a memo out telling everyone that I was leaving immediately. At this point I'm making up things when I get asked so far I'm:

Going to Rabbinical school.
Joining the peace corps.
Going into witness protection.
Going back to Israel(I'm not Israeli).
Going on tour with Foghat.
Joining the Broadway cast of Rent.

The really sad thing is that most people seem to actually buy into this crap.
