Huh, I've got a whole folder for this occasion!
Star Wars pin-ups, Doctor Who christmas cards, Zelda Valentine's day cards, oh and don't forget the christmas card depicting Superman punching Batman wearing a Santa costume - that's an important one.
Also I plan Call of Cthulhu tabletop campaigns just for fun (never actually found people to play one out with me).
I can quote entire episodes of Futurama and large chunks of Big Bang Theory. Seriously, I put it on mute and talk along.
I can tell you practically everything about the life and times of Scrooge McDuck and recognize every Barks comic by just one picture to one page.
I've got a book here called "The collected works of William Shakespeare". 200 pages of size 8 font in two columns. It's got everything.
I own several Star Wars EU books and most of the games.
A little Cthulhu statue guards my collection of Lovecraftian horror.
I make Monty Python's Flying Circus marathons.
Do you know the van from the film Fanboys? I'd kill to get my hands on it.
And finally... I'm now about to start working on my Aperture Science Enrichement Center radio wave receiver and replayer. Otherwise known as the Still Alive Salsa version playing radios. I love Portal.
