Today marks the 33rd anniversary of the birth of the incredibly talented geek and latter-day geek icon known as Felicia Day. Day first became known to the geek community for her recurring role as Vi in the final season of Buffy the Vampire Slayer, and since then has beamed up to geek stardom via her role as Penny in Dr. Horrible's Sing-Along Blog, the recently resurrected Dr. Holly Martin on Eureka and, especially, for her truly awesome web series The Guild. And, to top it all off, she's the evil mastermind behind one of the best YouTube channels going: Geek and Sundry.

All of us at GeekDad are huge Felicia Day fans, and wish her the very happiest of birthdays! We also feel that, as geeks, it behooves us to mention that Day's first name means "happiness," so that means her name is two-thirds of the phrase "happy birthday." Sort of.

Please join us in wishing Ms. Day a happy, geeky birthday, and many more! Leave birthday greetings in a comment if you're so inclined. And if you are yet untouched by The Guild, you owe it to yourself to remedy the situation.
