Dennis Finch is the sarcastic, power-hungry assistant to Blush publisher, Jack Gallo. He's sharp tongued--always quick with a mean (yet comical) retort and takes pleasure in cutting down his fellow co-workers at the magazine. He has a visible affection for Maya Gallo and for all the models that come in and out of the office. He loves to make jokes that include sexual innuendos and is particularly adept at sound effects, which he uses to punctuate his one-liners.

Finch is forever trying to curry favor with his boss, Jack, even though as an assistant he's less than proficient (unless sorting blue M&M's is a skill). In one episode, Maya asks him what he actually does at Blush and Finch replies in a whisper, "No one knows!" He never tires of trying to outdo whomever he feels is his competition at the magazine.

When Jack hires a magician as an assistant, Finch tries to perform extraordinary amateur tricks himself. In one instance, he goes so far as to announce, "Jack's dead. I'm in charge now!" In addition, he loves to play practical jokes; he switches Elliott's birthday gifts so it appears that Maya has given him a box promising a night of passion.

Finch is a cat fancier and former figure skater. For companionship, Finch kept a fluffy, white, award-winning purebred cat named Spartacus in his apartment. Finch took Spartacus to work one day, but it accidentally died in a head on collision while Jack and Maya were racing remote control model cars in the office. Finch had no idea how the cat died but had him stuffed and placed his mounted remains in the office.

A surprise to all, Finch admits to writing the Miss Pretty column for Blush, a column about women and love. Finch is easily hurt by the sarcasm of others in the office. When Jack asks if he's gained weight, Finch's expression drops. When told he cannot attend the Femmy awards, it's clear he's hurt, feeling like the second-class citizen he truly is at Blush.

When not on the job, Finch earns extra money teaching at Traffic School or as he likes to call it, Traffic Academy. He is also a member of the Future Magicians of America. When he isn't busy trying to bed the gorgeous models, he enjoys sci-fi conventions and cat shows.
