Axioms that aren't quite right

[mikesears]

I am considering authoring an article for my website about the dangers of applying clever axioms to all situations. I've come up with a couple and wanted to see if this collective think-tank can come up with more of them.

"The ground can't cause a fumble".

"The kicking team can't advance muffed kick".

"Penalize the offense where it hurts them the most".

What other axioms do we hear as officials that make us cringe because we know they don't apply to all situations as they suggest?
