At jump school

A young army private was home on leave. He was talking to his father about his experience at jump school while learning to be a paratrooper.

"Father" he says, "on my first jump, I froze up at the door of the plane. A big black master sergent standing behind me told me that if I didn''t jump, he was gonna cram all 12 inches of dick up my ass."

"Well, did you jump?" asks the father.

To which the son replied, "Just a little at first".
