You know you're a nerd when...

You see one of those "word verification" things (to prove that you're not a spammer), and the letters are "manhcl" and you immediately think, "oh, Human Hydrocloric Acid? Hmm...Do those have covalent bonds?" And then you smack yourself because it's nigh impossible for non-oxygenated molecules to have covalent bonds.

And then you realize you're just throwing words at the screen.
