At the funeral...
Right in the middle of lovemaking, the husband dies of a heart attack.
As the funeral arrangements are being made, the mortician informs the widow that he cannot get rid of her dead husband's rigor mortis hard-on which is sticking straight up in the air and if they don't do something, it will look odd in the coffin at the funeral.
The widow tells the mortician to cut it off and stick it up her dear departed's behind. The mortician can't believe his ears but the widow is adamant, so he does it. During the funeral, friends and relatives of the dead man filed past his coffin and were concerned to see a tear in the corner of his eye, but the widow assured them that there was no cause to be alarmed.
Just before the coffin is closed, the widow leans in and whispers in the dead man's ear, "It HURTS, doesn't it?"
