A friend of mine is in MED School and claims this is true.

One of the corpses he got to practice on was a priest who had accidently killed himself while autoasphixiating (playing with himself and cutting off his own air supply. Supposedly, it makes for a great orgasm).

Well, he did this in an army body bag,

in a dress,
wearing women's underwear.

and

In the underwear was a salad,
complete with Itallian Dressing.

Probably just a medical urban rumor
