Harry and Marv are greedy robbers who rob for money and cash, but are also very bad at being criminals. Individually, Harry is shown to be the more intelligent, no-nonsense and leader of the duo, but his short temper, overconfidence, the fact that he is unintelligent in his own right, and tendency to underestimate Kevin results in him not thinking things through. Him being the leader, Harry also often keeps Marv in line by stomping on his foot or telling him to "shut up".
