Kim is a friend of Leo Markus.
Kim is very short, and enjoys biking.
He appears in It's the Gay Pumpkin, Charlie Brown when Leo fixes him up with Will for a double date biking in the Catskills.
Will is initially uninterested in Kim due to his diminutive stature, although Jack refers to him as a "travel-sized homosexual" and says "in ten years, they'll be making them all that way." 
Kim is cheery and upbeat, undeterred by Will's cantankerous nature and even gives him a foot rub when he suffers a biking accident.
In the closing credits of the episode, Will and Kim are implied to have slept together.
