1. The fact that my husband insists on using shampoo...to wash his bald head.
2. The "Darwin fish." C'mon. If Darwinian theory is so awesome, come up with your own symbol instead of trying to be all ironic and whatnot by playing on the Ichthus. (But then I get even more annoyed at the Ichthus EATING the Darwin fish...Stop the madness people.)
3. Quadratic equations. If ax² + bx + c = 0 then blah blah blah.
P.S. My daughter wished my husband a "Happy Hispanic Heritage Month" as he left for work this morning. Awesome.
