The Rule of Funny states that something can break the laws of physics if it gets a laugh or is meant to be funny or amusing. As far as I can tell, this is basically toonforce.

The Rule of Cool states that something can break the laws of physics if it is suitably cool and/or awesome. I am now coining the term "coolforce" and may begin using it in debates.
Cloud should not be able to wield the Buster Sword due to its size, but he is able to through coolforce. When he attacked Bahamut, he should not have thrown it downward, but himself upward, due to him wieghing much less. Coolforce allowed him to do this.
Etc., etc. so on and so on. I can concievably put together an argument to shut down nearly any character through the use of any one of the Rules of Drama. Kratos' feats? Coolforce. Kain's feats? Coolforce. Dante? Toonforce, since he's pretty funny, but he also uses coolforce.
If toonforce keeps being used as a viable argument, I'm going to continue this.
