It’s time for another Joss Whedon-related birthday! Today’s birthday boy is Tom Lenk, who is probably best known for his roles on both Buffy the Vampire Slayer and its spin-off Angel. Lenk also worked with Whedon on The Cabin in the Woods and Whedon’s adaptation of Much Ado About Nothing. Outside of his Whedon work, Lenk has also appeared on such TV shows as Six Feet Under, House, How I Met Your Mother, Nip/Tuck, and The Guild, and in films including Boogie Nights, Date Movie, The Number 23, Transformers, God Bless America and Argo. He turns 37 today.
