Justin has learned that falling down is funny. Ah, he has officially started his journey into manhood. People getting hurt is funny. He will soon roll off the couch onto the floor while watching other's home videos on TV. The ones where the kid hits the dad between the legs will have him so hysterical that it will almost make him pee.
Now we just need the bathroom humor to begin and he will be another step closer. I am so out numbered in this house!
