Two Army boys

Two Army boys, Leroy & Jasper, from the hills of Kentucky were promoted right from privates to Sergeants because of their great marksmanship with rifles.
Not long after, they're out for a walk and Leroy says, "Hey, Jasper, There's the NCO 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'm a gonna sit down and have me a drink." "But we's privates," says Jasper. "Are you blind, boy?" asks Leroy, pointing at his stripes. We's sergeants now, so hush your mouth!"
So they have their drinks and pretty soon a hooker comes up to Leroy. "You're cute," she says, "and I'd like to date 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, "why did you give me the okay sign?"
"Well Leroy, in the dictionary, it says gonorrhea affects only the privates." He points to his stripes. "But we's sergeants now!"
