Back before "don't ask don't tell" ...

... this gruff old drill-sergeant was having the new recruits count off by fours.

So everything is OK until the fourth round, when the guy who says "one" says it in a very high, girlish voice.

So the drill-sergeant says - "OK - we're gonna try that again, and this time NO jokes."

So they do it again, and sure enough, the thirteenth guy says "one" in the same high girlish voice.

So the drill-sergeant stops them again, and to make sure he's got the right recruit to discipline for screwing around a second time, he says to them: "OK, who's one?"

And the thirteenth guy says "I'm one! Are you one too?"
