When I was young we were so poor that the only heat in the house was the fireplace, so in the winter we would all sleep on pallets on the floor in the living room. The house was so old that the wind would blow through cracks in the floor & ruffle the quilts we were lying on. One morning when I woke up I found lots of little "glass" balls lying around on the floor. I gathered them all up and lined them up on the fireplace hearth trying to figure out what they were while warming up.
Suddenly they started to melt, POP POP POP, and an awful stink filled the room.
THEY WERE FROZEN FARTS!
