If it's not against the rules it should be. That's how the rules get created in the first place. Invent funny crimes, pass funny laws.
Obviously the first person to open the thread (Ash's by?) meant it more in a sarcastic manner. Everyone else made it very official.
Rule idea 1.1 if a player doesn't avg 50 in test he shall not get an OT. If a player doesn't have a SR of 150 in T20, he shall not get an OT. If a player avg 50 with the ball and has econ over 5, he shall not get one.
