Wow, this is a hard one. So I'm going to go ahead and say....
Doctor Who! No surprise there I think. Mad love for this show.
I'm gonna go ahead and make a list of "mentionables" though because there are so many shows I can't live without:
1. Johnathan Creek
5. How I Met Your Mother
7. The Simpsons
Think that's all...
I watch way too much TV (^.^)
(EDIT: Must add - RIP Elisabeth Sladen, you were the best companion and the most loved Doctor Who actress of all time. You left the world far too soon and will be sorely missed by fans the world over. ♥)
Ohmygosh I forgot HOUSE!!!
