Oops, sorry. Mea culpa. I just Googled for “mystery science theme song lyrics” and grabbed one. Never realized that those could have junk. (How do you “check” for that, anyway?)
Came in here to post a neat one I saw the other day:
R U BUKLD
I saw a VW Beetle with the plate “KAFKA1” (I guess just plain “KAFKA” was taken).
Just the other day, I saw 5TH RCK.
On a Saturn.
Ha!
Shouldn’t that be “6TH RCK”? 
I did see chmd 755 the other day on a plate.
I got a personalized plate so I could remember the plate number.
There’s a black jaguar I see occasionally in my neighborhood that I like: JAG NOIR
Pretentious, but funny.
I saw one yesterday that had CR8TIVE. You would think they could have come up with a better one than that unless it’s false advertising. 
My non-vanity plate came out 569 WEE.
But I can easily remember it, and all my friends tease me because oh how i say it:
569- Weeeee! Like a playground rhyme 
I am such a dork.
Oh and a really cool one 10SANE1…get it?
Oh and the worst, was this terrible amazon bleach blond in High School who got a new red Mitsubishi Eclipse sport car:
A BABE
How vain and self absorbed can one be?
Due to others accusing her of false advertisment, she did not renew it the next year.
Also, mensa is Latin for “table”, while the Spanish equivalent is mesa. So the joke works on that level as well!
Corii: Guess that C6H12O6 plate makes the car (even if it’s not an IROC) one sweet ride…
I still don’t get these:
FU INLE
VAXVMS
ZVBXRPL
B15UBS
P195SUK
C6H12O6
(Man, I’m dumb.)
I once knew a girl who had a blue Horizon. I asked if she’d ever thought of getting a plate that said BEYOND. She said yes, many times, but she couldn’t afford vanity plates.
These are indeed obscure. VAXVMS is the name of an operating system for Digital Equipment Coporation’s VAX computers, which are long out of production. I would guess that C6H12O6 is a chemical compound, but my organic chemistry is too weak to tell you which it is. You got me on the others, though.
Well, I think “P195SUK” means “Pigs suck”. As in cops. The “1” is an “I”, the “9” is a “G”, and the “5” is an “S”.
I think. No clue about the others, though.
While raising 4 children, my mother thought that WATAZU on the family stationwagon was a good idea. My personal favorite was on a nice Black Buick Grand National, it read BKNBLK. And you could hear the AC/DC for miles.
C[sub]6[/sub]H[sub]12[/sub]O[sub]6[/sub] is sugar.
I saw a new light green VW Beetle with the plate WASABI. Then there was a PT Cruiser painted with cow spots that said PTMOOSER. I thought both of those were pretty cool.
I saw a silver sports car with the plate AG AMMO.
Sweet!
The Black Rabbit of Fu Inle was some sort of mythical Death figure for the rabbits in Watership Down
Which one(s)?
