Kick Wobble Wobble Wobble

There's this guy, John, in my taekwondo class and well... he isn't the fittest person in the world, if you know what i mean. Now i don't discriminate against a little gut, but this guy has like a... superXXLgut. Everything else is normal-ish sized though. We were free sparring, and everytime we end up together i aim for the belly-wobble. Since it's meant to be non-contact, i kicked it properly right at the end, not so it hurt, but just to satisfy my need to know how exactly "it would react" - as expected it wobbled as if in slow mo' like old jelly. He looked at me with a very surprised expression on his face =) Highlight of my day. I am so mean sometimes.
