Stick it where?

I just received a voice mail from a friend (who shall remain nameless) telling an amusing "What I meant to say" story (of which he reminded me that I have several of my own):
He had two Mormon missionaries at his house, sitting at his table. What he meant to say was,

"Could you stick that rotten banana down the garbage disposal?"

What he instead said was:

"Could you stick that banana in the glory hole?"
