Guy vists a doctor and tells him: Doc, I can't stop singing 'The Green, Green Grass Of Home.'" The doctor says, "That sounds like Tom Jones Syndrome." The patient asks: "Is that common?"
A nun walks into a liquor store and says, "Give me a pint of brandy." The guy says, "Sister, I've never sold alcohol to a nun." She says, "It's for the Mother Superior, she's constipated."
So he sells it to her. Later that night, he walks out, and there's the nun on the stoop, with the empty bottle, drunk as a skunk, singing and laughing. He says, "Sister, for shame. You told me the bottle was for the Mother Superior's constipation."
The nun says, "It is. She's constipated, and when she sees me, she's gonna shit."
