Mr. Klotz is Roger's Father. He‘s divorced from Mrs. Klotz and lives in Bloatsburg. He’s a professional clown.


Roger's father is goofy and a jokester, but he does make good judgement calls regarding the well-being of Roger.


Mr. Klotz visits Roger in the episode Doug's Movie Madness, where he compliments on how mature Roger is getting. Despite this, he forbids him to watch the movie Targetman, on the grounds that it's too violent. When Roger attempts to sneak into the theater and watch it, his father drags him out of the theater, telling him that, even though he is a higher tax bracket, he's still Roger's father and loves him but reinforces that he's not going to watch the movie.
