I've always been in good shape, tho I love ice cream and other goodies. I never order a soda with ice cream tho, but if I did, I'd order diet just becuase I acquired the taste for them years ago,
and now can't stand regular sodas (except root beer and Squirt).
I saw an interesting LARGE guest last year. My wife and I got married in the park and in the morning we were having fun, going on rides. We were in the SAP line going into Pirates and ended up waiting for 45 minutes while no boat left the doc. Came to see (as people in front of us gave up and left in disgust) that a HUGELY fat woman was trying to get seated in a boat. I say TRYING, because she was so fat <chorus of "How fat was she?"> that her ass hit the top of the seat back, and her prodigeous belly hit the back of the seat IN FRONT OF HER, and she couldn't get any further down into the boat, and couldn't even touch the seat! After another 15 minutes of attempting to shoehorn this Hostess Ho-Ho hippo into the ride boat, they finally gave up and with the help of two construction derricks and Hercules himself, they hauled her 1.5 cubic acres of useless flesh out of the boat and back onto the dock.
The result? CHEERS FROM THE LOADING DOCK! THE GUESTS ALL DID A WAVE!!!
One would hope the shame of that encouraged her to diet...
