This thread reminds me of a joke I heard.
A man equipped with a parachute, jumps out of an airplane.
On the way down, he pulls the rip cord and discovers it isn't working and begins frantically struggling to fix it.
As he plummets downward toward the earth, he sees another man in the distance who, for some reason is flying upward at a rapid pace.
As the two pass each other, the man with the parachute shouts " HEY MISTER...DO YOU KNOW ANYTHING ABOUT PARACHUTES ??? "
The other man shouts back " NOOO.....DO YOU KNOW ANTYING ABOUT GAS STOVES??"
