Since we've wandered totally OT, I couldn't resist throwing in my favorite story on a related topic to David's love.
This guy's not skydiving, just practicing parachute jumps. On one jump, his chute failed to open, and he couldn't get the backup to work properly either. As he looks down to see the ground rushing up at him, he notices a man rising towards him as fast as he's plummeting downward.
As they pass, he yells out "Hey, you know anything about parachutes? I desperately need help!"
"No, sorry -- you know anything about propane BBQs?"
