When I was in boot camp at a field exercise I had to go to the drill sergeant tent to ask for something (can't remember what). Because we couldn't just walk in the tent the directions were given we need to yell "DING DONG" really loud if we want something. I yelled "DING DONG" and was told to yell louder a few times. After hearing a bunch of giggling in the tent my drill sergeant comes out:

Drill: "have you seen the wizard of OZ?"

Me: "yes drill sergeant"

Drill (quietly): "I'm going go go back in the tent. Next time you need to ding ding to the tune of the witch is dead song, you know: ding dong di di ding dong, ding ding dong di di ding dong"

Me (5 seconds after he goes in the tent):

"DING DONG DI DI DING DONG DING DING DONG DI DI DING DONG, DING DONG DI DI DI DING DING DONG"
