This one is just as good or bad. My cousin sent it to me yesterday. It is also alcohol and clergy-related:

Subject: Mother Superior

A 98-year-old Mother Superior from Ireland was dying. The nuns
gathered around her bed trying to make her last journey comfortable.
They tried giving her some warm milk to drink but she refused it.

One of the nuns took the glass back to the kitchen and remembering a
bottle of Irish whiskey received as a gift the previous Christmas, she
opened it and poured a generous amount into the warm milk.
Back at Mother Superior's bed, she held the glass to her lips. Mother
drank a little.... then a little more. Before they knew it, she had
drunk the whole glass down to the last drop.

"Mother," the nuns asked with earnestness, "have you some instructions you wish to give us before you depart?"
Raising herself up in bed, she whispered, "Don't sell that cow."
