This is an old family story. My Aunt Helen is one of those quick witted punsters who speaks before she thinks. Grandpa is in the hospital for what turns out to be the last time before his death. He knows he hasn't long, but something comes to mind, and he can't resist the complaint; I have forgotten about what. He ends with "At least I won't have to put up with much longer." Aunt Helen without missing a beat says, "Yeah, you lucky stiff." Aunts and Uncles all of a sudden stifle caughs, and have to blow their noses, or at the very least inspect their shoes. Of course Aunt Helen can't figure out what's going on.
