"Ref" Jeffrey Maluso (referred to as Jeffrey Malk in Locked Up) is a disgraced referee, a bouncy house manager, reality tv show contestant and prisoner, who frequently attempts to make friends or "lock down plans" despite constant rejection. Some say that he is a parody of disgraced NBA referee Tim Donaghy.
Season One[]
Jeff referees a basketball game between the Oakland Raiders and the San Diego Toreros, sponsored by The San Diego Diet. Jeff frequently harasses the players, attempting to "lock down plans" with them, despite their apparent discomfort. He reveals that his father abandoned him as a child. ("San Diego Diet")
