It's-a Round 12!

Right, so Knight Rider pretty much walked Round 11 and left Jupiter out in space somewhere.

Not too shocking I guess, but how will it fare this time around?

Knight Rider

D-dun, d-dun, d-dun.

vs.

Luigi

It's-a him, Luigi.

Round 11 - SatNav ain't what it used to be.

 Round 10 was pretty close, but Jupiter trumped House by a couple of votes.

What was missing from the pic of Jupiter?
I removed the unsightly moon Ganymede from the shot.

See?

 This round:

JupIter

Big. Round.

vs.

Knight Rider

Small and roundy? What?

So vote for Jupiter or Knight Rider in the comments.
