Adding insult to injury

Words of warning: After you have been sitting in an innertube on the lake for a while and decide to get out make sure that you can move in the inner tube before trying to climb the ladder at the dock. If you don't you might find yourself stuck in the tube, sort of bent over with your behind sticking out the back of the tube. This may cause fellow lake devotees to quip, "Does this innertube make my butt look big?"
If this happens to you, consider yourself warned!
(PS: this may also cause you to get a stomach ache from laughing so hard while doubled up in the tube where you can't get a good breath!)
