It wasn't so much the answer, as it was the offer to demonstrate on the Recruiter.
(Honestly though, I think it was addressing the Marine recruiter as, "Sailor" that finally did him in.)
After the Gunny threw him out of the Marine recruiting station, the DUmmy went next door to the Navy recruiter.
He asked the recruiting Chief, "Do you have an opening for a Butt Pirate?"
What followed is best described as "the first pre-enlistment blanket party."
