A woman was in a gambling casino for the first time. At the roulette she says, "I have no idea what number to play."
A young, good-looking man nearby suggests she play her age.
Smiling at the man, she puts her money on number 32.
The wheel is spun, and 41 comes up.
The smile drifted from the woman's face and she fainted.
