Clyde was famous for scoring four triples in a game. In the film, Magnet says that Clyde is the "fastest guy in the Majors". The shoes Clyde wore during the game were the ones Caveman (Stanley Yelnats IV) was accused of stealing.
At Stanley's trial, it was learned that Clyde Livingston had been an orphan living at the same orphanage were the shoes had been stolen from. At the trial, the lawyer asked him to tell them a little something of his background. Besides the fact that it was his donated shoes that were stolen, what other connection might he have had with this case?
"Well, I was an orphan. I grew up in that home. I don't understand what type of person steals from homeless children." He glared at Stanley and said, "You're no fan of mine." Stanley felt really bad that he stole Sweet Feet's shoes and that his hero thinks he is a bad person.
Clyde later realized that Stanley didn't steal the shoes and he was shown in both the book and film as attending the party at the Yelnats' home. The family and the guests watched the commercial for "Sploosh", made by Stanley Yelnats III which starred Clyde.
