Ok - so tonight, I'm working on some stuff on the computer, and Jacob comes in and says, "listen to this" So he starts jumping up and down, and it sounds like he has a half-full water balloon under his shirt. I ask him, "what is that?" and he says, "My belly - I've been drinking lots of chocolate milk!" and he starts jumping, and sure enough, you can hear the sloshing. I lift up his shirt, sure enough, it's just his belly. So - - of course, I make a video. . .then I told him he should probably 1)quit jumping and 2)don't drink anymore for now.
So - - turn up your sound, and enjoy. . .lol
