In general, Finch has been described as "a self-centered horny pig who'd stop at nothing to get laid." He is discovered to be well endowed but does not realize this until Jack and Elliot bring it to his attention; they react with disgust when Finch says he always believed he was merely "a little above average" as he'd only seen other naked men in porn movies. Surreptitiously, Dennis writes articles for the "Dear Miss Pretty" advice column. Dennis used to compete in figure skating, as revealed in the season 3 episode, 'Softball'. Dennis also likes to collect action figures and ceramic kittens. He lives in an apartment, number 803, in New York City (Manhattan), which was formerly Maya's apartment before she moved in with Elliot.
