Must be a toddler thing

Big guy has this habit that must be a toddler thing. He will purposefully throw something of the floor and the yell, "uh-oh!" and each time he does something like this, I calmly explain that if he does it on purpose, then it's not an accident. Yet, he continues to do it. Must be a toddler thing, as in, it's out of his control the things falling, but clearly it's an accident!
