That sort of reminds me of days of old, when I saw a friend of mine throw a five dollar bill down the hole of an old outhouse.
I said, "What the hell are you doing?"
He replied, "I dropped fifty cents down there in the hole. You don't think I'm going to reach down in that stuff for just fifty cents, do you?"

In the army, helped to lower a guy into a "long-drop" to retrieve his wedding ring.
"One guy lost his dentures in the john. He was so happy to get them back."
Wouldn't that give a true meaning to "Sh!t-Eating Grin"???
