Okay Ron, Harry, very funny... I guess your leg isn't sore enough to keep you from pulling a mean prank. Who are you kidding Ron isn't good enough with his spells to pull something like this off.
Okay... so thinking logically Ron wouldn't know how to use this thing, being a muggle device. Harry... Someone... please tell me there's somebody here. This can't be his doing can it? I would be dead instead... right?
