(The Great Humberto, Humberto) A television show airing Monday nights which Dudley enjoys.

The Great Humberto was a television programme that Dudley Dursley, cousin of Harry Potter, liked to watch on Monday nights when he was eleven; however, Harry seemed to think that it was stupid. When Vernon Dursley took the family on a trip to escape from the Hogwarts letters trying to reach Harry Potter, Dudley complained to his mother, Petunia Dursley, that he wanted to stay somewhere with a television so he could see this show.
