Now, I know many of you out there who are doing the daily blog posts have talked about crafting, chocolate etc...as your guilty pleasure, but mine might be one not many of my readers out there share.
Red Dwarf, Star Wars (first 3 films only!) etc etc.
I think it all comes from being a bit of a geek all my life, well you can't teach science for over 20 years to teenagers without enjoying the subject!
My current fave isn't Sci Fi as such, but it certainly falls into the category of geek TV; The Big Bang Theory.
