That's not what fat people's feet look like.

When I was a kid, and I went to the beach with my family, I would always stomp as I walked in the sand. My idea was that someone would see my footprints later and say "Wow, that guy must've been really fat."
I recently found out that this is not the case. Fat people's feet are shaped differently than people of a healthy weight. You can imagine how devastating this was for me. Years of hard work down the drain. Anyway, fat people have no arches in their footprint, because their arch collapses after years of holding up all of that fat.
So now, when I go to the beach, I have to smooth out every arch with my heel. It takes me forever to get anywhere. But everybody thinks I'm really fat.
