Robert Jefferson

Robert Jefferson is father of Rowley Jefferson and the husband of Mrs. Jefferson. He appears as a minor antagonist. He is one of the wealthiest people in Greg's neighborhood, as well as the least respected in his neighborhood. In the movie, he is played by Alf Humphreys. He doesn't like Greg because one time Greg and Rowley made a secret language (which Greg used to insult him) but Robert easily cracked the code.

Personality
He is an extremely overprotective parent and won't let Rowley play any video games with the slightest bit of violence or fighting in it, as he sees them as things that could change Rowley into a different person. He won't even let Rowley use the internet. He is extremely rude and cannot accept criticism from people he dislikes, as seen in Dog Days. In the events of Dog Days, it is shown that he can simply restrict people he dislikes from ever entering his country club again if they dare give any type of criticism about him or his property.

Appearance
Greg depicts Mr. Jefferson with afro-style hair, black shirt, and long pants. There has been an illustration of him in pajamas, but this was only shown in Dog Days.

He returned in the film version of Rodrick Rules but has no dialogue. He only appears to pick up Rowley after Rowley had sat on the tin-foil ball covered with toothpicks that Manny made for Greg and when after Rowley freaked out from watching the movie The Foot, Greg was forced to apologize to Robert for choosing an inappropriate movie.
