The word is out about town,
That Rock Hudson loved it in the brown;
He eschewed the nubile maids,
And now he has a case of AIDS.

Those who finally got him,
Penetrated his well-rounded bottom.

While down in Tijuana Town, when asked:
"Hey meester! Do you want to fuck my seester?"
Rock replied: "Hell no! Sock it to me in the keister!

-- doggrel, circa 1985
