Luke: Man of Mystery

I have now spent two days cleaning out my children's rooms.  For some it may be drudgery, but I actually kind of salivate at the chance I get during the first days of school when my children leave and I get to throw away, I mean, "re-organize" their stuff.  I finished Luke's room yesterday and, while cleaning out his backpack from the end of school back in June, I found three things in the front pocket.  Three things that have completely baffled me and made me think I am sleeping in a room next to a total stranger.

1. 

A playing card (four of diamonds) with a diagram of the Tulsa, OK airport on the back.

2.

A foam bookmark with the greatest school picture in the history of school pictures ever stuck to it.

(I may or may not be making this into a Christmas ornament for my tree this year.  

I don't know who this guy is, but I gotta have him.)

3.

A baggie filled with a disgusting sock.

And I thought Cindy having 154 fun size Skittles wrappers under her bed made me nervous! While I do some reconnaissance on these items, go ahead and make your guesses as to why these were in his backpack.  If you go three for three, I will give you a playing card with a diagram of the Tulsa, OK airport on it.  What can I say? I have connections...
