Since this has strayed off the Winni-path, I'm going add a couple...
"SHDOWFX" (Hint: named for a famous fictional horse.)
"22MANY" (Guess what kind of vehicle that was on....)
"NH2STAY" (Self-explanatory. The vehicle is registered here in Alton.)
"SWTNLW" (Hint: It comes in a pink packet.)
"STOL3N" (Self-explanatory. Imagine being the cop that has to call that one in!)
"IFARTED" (No. I didn't. But how did they get that approved?)
Which leads to the personalized plate I had on my Ford Festiva in high school....
"FUBB" (Yes, it's an acronym. Google it if you don't know it.)
