The Last Supper: Where's Judas?

In Fr. Jay Toborowsky's post, Spy Wednesday, he mentions artistic depictions of Judas at the Last Supper, and that reminded me of something I've done for as long as I can remember when looking at Last Supper images.

Before I can take in the piece as a whole, I Must Find Judas. I can't enjoy it until I do. It's like I'm compelled to play a version of Where's Waldo? every time I see the Last Supper.

I quickly scan through all the apostles, holding my breath until I find him.

Who's missing a halo?



Or sporting a just-sucked-on-lemons countenance?



Or sitting apart from the others?



Or clutching a money-bag?



Then ... a-HA! There he is! OK, now I can take it easy and look at the rest of the piece.

So, um ... anyone else do this, or is it just me?
