This little anecdote was told to me by fellow counselors at Kanakuk, a summer camp I used to go to/work-at, in Missouri....the names have been changed because it was 10+ years ago, and I don't remember them.
Jane and Jill were at a Denny's, catching some cheap grub, having a nice conversation. The next table over, an old woman and husband were having a lively conversation.
Jane excused herself to go to the bathroom, went into the stall, and started to do her business. Over the wall of the stall, she hears the little old lady speaking to herself,
"Corn?!? When did I have corn?"
