Leonard is a security guard at Sacred Heart Hospital.
Leonard has a hook for a hand, which he got when he got his right hand stuck in the hospital ice machine. He got a $5,000,000 settlement for the loss of his real hand. ("My Best Friend's Baby's Baby and My Baby's Baby") He is very tall, and a running gag is that he is most recognized by the hospital staff by his giant afro, and barely noticing his hook.
