Just fooling around with blanks

Hey suppose I asked “What do Bill Maher and [name omitted] have in common?”
Because I said [name omitted] (who will remain blank), no one would know what I was talking about, so they would draw a complete blank. About Blank. What if I said that this Blank was having a huge blog war with another Blank. That both of these Blanks have well known policies of declaring absolute war against anyone who criticizes them. Would that make it clear who the blank was and why it is a fruitless and foolish endeavor to fill in the Blanks?
If so, then let me restate the question.

Q. What do Bill Maher and Blank have in common?
A. Both claim to be libertarians!

Har!
I know that’s not funny, and jokes like that could get me in trouble with one or the other Blank faction, and I’d hate to be in trouble with the Blank faction just because I’m having fun fooling around with blanks.
But would I have any defense against the Blanks if the joke happened to be true?
Is that it? Are jokes supposed to be lies?
Can’t they be about lies?
