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