Leroy and Jasper have been promoted from privates to sergeants. Not long after, they're out for a walk and Leroy says, "Hey, Jasper, there's the Officer's Club. Let's you and me stop in."
"But we's privates," protests Jasper.
"We's sergeants now," says Leroy, pulling him inside. "Now, Jasper, I'se gonna sit down and have me a drink."
"But we's privates," says Jasper.
"You blind?" asks Leroy, pointing at his stripes. "We's sergeants now."
So they have their drink, and pretty soon a hooker comes up to Leroy.
"Your cute," she says, "and I'd like to screw you, but I've got a bad case of gonorrhea."
Leroy pulls his friend to the side and whispers, "Jasper, go look in the dictionary and see what 'gonorrhea' means. If it's okay, give me the okay sign." So Jasper goes to look it up, comes back, and gives Leroy the big okay sign. Three weeks later Leroy is laid up in the infirmary with a terrible case of gonorrhea.
"Jasper," he says, "what fo' you give me the okay?"
"Well, Leroy, in the dictionary, it say gonorrhea affects only the privates."
He points to his stripes. "But we's sergeants now."
