Eh, if some fat guy wants to lose weight, and thinks DDR is a great jumping off point, whatever. That's cool, at least he's doing something that doesn't involve sitting in a chair.
Now, that guy dancing in his webcam - while sitting - that's funny.
OMG he did a cross-over step when he really should have done the twisting plant step!! LOL what a noob!!
But seriously, no ... I see nothing funny about it.
What I thought was funny, was at the gym the other day, some guy was walking at the slowest speed possible on a treadmill playing a Gameboy. It was too many conflicting messages for my brain to process.
