A small boy walks into his mother's room and catches her topless.
"Mommy, Mommy, what are those?" he says pointing to her breasts.
"Well, son," she says, These are balloons, and when you die, they
inflate and float you up to heaven."
Incredibly, he appears to believe this explanation and goes off quite
satisfied. Two days later while his mother is making tea, he rushes
into the kitchen. "Mommy, mommy, Aunt Eliza is dying!"
"What do you mean?" says his mother.
"Well she's out in the garden shed, lying on the floor. Both of her
balloons are out, Dad's blowing them up, and she keeps yelling,
"God, I'm coming! God, I'm coming!"
