DE-odorant?

Why is it called de-odorant when it's actually fragrant? It doesn't remove odor, it covers it up (and adds its own, which sometimes, in some cases, might be worse than what it's trying to cover). My son suggested perhaps it used to be called odorant, as in back in Boston when people would say, "Go get de odorant from de store!" And it became shortened to "de-odorant" and then simply "deodorant" (ok, he made up the short version, and I expanded it).

Oh, and why is it "anti-persperant" and "de-odorant"? Why the two differing prefixes? And why is it prefixes and not prefices (you know, like "matrix" and "matrices")?

For those who may have missed the Wednesday Night Jokes (because you don't work in our AWANA office), here you go:

• pediatricians: men of little patients
• insanity: the desire to have children

Ok, not so good, perhaps. How about this one, then: "ABCDE" - a phrase you might hear when a striped insect visits an ophthalmologist or optometrist. (Think about it for a while if you don't get it right away, and perhaps try saying the phrase out loud, sort of slowly; leave a comment if you don't get it and I'll explain in more detail.)

Still waiting on the seatbelt part I bought off e-bay (it took a long time for the paypal transaction to clear). This one-car lifestyle isn't exactly inducive (yeah, I made up that word) of ease-of-... well, life. Ah, soon, soon... anyone got a free (working) car they are looking to donate to a family in need? :) I know, I know... learn to be content, all that...
