Danny DeVito :: Character Guides

Frank is Dennis and Dee's father. After deciding to divorce his wife, he pays his children a visit, hoping to get more involved in their lives. Once he shows up, it becomes very clear why Dennis and Dee turned out the way they did. Frank is quite sordid and has no problem referring to his wife as a whore. There is some truth to this accusation, though, considering that she had an affair with another man many years ago. This brings to light that Frank is not even Dennis and Dee's biological father. However, Frank then learns that he's Charlie's father due to a one-night stand he had thirty years ago.

Initially, Frank simply wanted to be accepted as a part of their group. However, the enormous amount of money he managed to accumulate over the years gives him a certain power over the rest of the guys. When the opportunity arises, he buys part of the bar and blackmails the rest of the gang into allowing him to stick around.
