Tubes are the bane of every public lake water skiers existance. But these people have figured out how to use a tube in a way that does not make me want to stab them with dull knives. I am already trying to figure out how to set one of these up on my lake. Of course my lake is currently imaginary...and it has a space ship, so why would I need some dumb crap like this? Huh??!!?? Tell me! Yea, I bet your lake does not have a space ship at it. Loser.
