This was sent by Glaurung, who gets awarded for both submitting a serious
bug that was funny, too:

the funniest most serious bug i can recall was an invulnerability bug.
The thing to do was to use dark meditation as an evil priest. Your soul
departs your body, and then you go and get killed as a soul. You get
back alive and go recover your corpse. After that you wear your corpse
and go around killing monsters, all the damage goes to the corpse.

Funny bug, not easy to come by, and the added bonus of getting to walk
around in your own corpse is pretty funny.
