Oh man...I'm sorry but I can't help but laugh at that.
Well, that kid's only two, and I remember sticking stuff (that won't get stuck lol) down the toilet when I was little ^^;;. I'm surprised that the boy didn't make a fuss! I thought most two-year-olds would start whining or something x_X.
So I'm guessing their toilet is small (ew xD) or the kid's head is unbelievably big O_O
