He tells Eddie that the guy Eddie is when he drinks isn't a friend of Eddie or Waldo. He tells him off, saying that if anyone drinks at a party and insults friends, they are no friends of his. The third time was in Tips For a Better Life, when Waldo refused to let a recently kicked out Eddie move in with him. The second was in Talk's Cheap, when he called Laura, Eddie, Myra and Myrtle back to their senses with Stefan’s help. The first was in A Test of Friendship, when he told Eddie off that cheating is wrong and he should've known better. Despite his lack of intelligence, he has shown that he has a sense of morality in three key episodes. His catchphrases include: "Cool", "No prob, Bob!", and "Sup!". Waldo discovered, however, in Food, Lies, and Videotape that he is a culinary prodigy which led him to get an A in home economics which was a big thing for him to swallow. Waldo's most famous trait was his dimwitted-ness and uncanny ability to misinterpret a simple question, comment, or directive. Waldo has also been afraid to walk, until he was ten.
Waldo has reached the point where he even annoys Urkel. While Urkel was the resident nerd, Waldo was the resident idiot. Like Urkel (the show's most famous character), Waldo was an outlandish, almost surrealistic character. He once started off as the sidekick to resident bully Willie Fuffner, but has grown out of it. For most of the time Waldo was featured on the show, he was friends with Eddie Winslow (the son of the show's main characters, Carl and Harriette Winslow) and the Winslows' quintessential nerdy and bothersome neighbor, Steve Urkel.
