I love the birthday cake scene in Tempus Fugit...
Mulder: I didn't know it was your birthday, Scully.
Scully: Mulder, you've never remembered my birthday in the four years I've known you.
Mulder: That's the way I like to celebrate. It's every four years, like dog years.
Scully: Dog years? Thank you.
Thanks for the pics Nicole, love the one with Mulders cheesy grin
