Crazy Creed

Creed Bratton is a taciturn but creepy Quality Assurance representative at the Scranton branch of fictitious paper distributor Dunder-Mifflin. As the result of his drug use during his career as a rock musician in the 1960s, Creed has a phenomenally poor memory; he hardly remembers the names of his own co-workers. Little is known about Creed's life outside the office. The scattered details which emerge are invariably bizarre. (From Wikipedia)

Kooky Creed facts:

following his rock career, he had his own radio show in the 1970s as "DJ Wacky Weed Creed"

karaoked to himself in the episode "A Benihana Christmas," performing his "Spinnin' N Reelin'" (from his album The 80's)

may have spent considerable time in jail as well as being homeless at some point (when he is having his photo ID taken, Creed turns to his side, as though he was having his mug shot taken)

episode "Casino Night" provides the first glimpse into Creed's passion for stealing

admitted in a talking head interview, "I love stealing things"

The Grass Roots 1967 song "Let's Live For Today" (#8 in the U.S.); note how the audience laughs when Jimmy Durante says the name of the band. I find that odd.
