tennis balls? (was: today's quiz)

Randy and fellow fiends:

I just got the digest (#1399) and Randy's proposals for my quiz.  Regarding 
which XJ6 it was... I don't know.  In fact, I'm not  100% sure it was an 
XJ6, but I am sure it was a jag.  That may in fact make the whole thing a 
bit unfair, but see my hint #1, just posted.  Who said this was supposed to 
be fair, anyway!?

Tennis balls?  TENNIS BALLS?  I like it, but...that ain't it.
