Welcome home party and dance joke

Following some duty overseas, the officers at the Fort were planning a welcome home party and dance for the unit. Being an all male combat force, they decided to request coeds from some of the surrounding colleges to attend.

The Captain called Vassar and was assured by the Dean that arrangements could be made to send over a dozen of their most trustworthy students. The Captain hesitated, then said, "Would it also be possible to send a dozen or so of the other kind?"
