Ah ha ha!

Actually, only SCUBA and LASER (of Jon's list) are 'acronyms' as such. An acronym is an abbreviation that forms a pronounceable word. The others are merely abbreviations, or what the word is (it's a lot like acronym) that I can't remember.

Oh, I looked it up:
A&W is the initials of the last names of the guys who founded it, Allen and Wright.

But I think it should be Awl and Widget. Or Algae and Weeds. Or... Asterisk and Whatnot.
Of course, to an extent, those are my initials too.

Okay, I'm wrong about acronym. Odd.
