Olympic gymnasts Paul and Morgan Hamm (search) returned to the high school they attended to thank hundreds of supporters, then jumped on an antique fire truck and took part in a parade in their honor.

Screaming girls ran up to the Hamm brothers with roses tied with red, white and blue ribbons during the parade, which was attended by about 1,000 people.

Paul Hamm won a disputed gold medal in the men's all-around gymnastics competition, and the 21-year-old twins both earned silver medals in the men's team competition. Paul also won a silver on the high bar.

"I would personally like to thank everyone in Waukesha and Wisconsin for all the support that I received during the Olympics and also during the controversy," Paul Hamm said Wednesday at the Waukesha South High School field house.

Because of a judging error in the all-around competition, the gymnastics governing body asked him to give his gold medal to South Korean gymnast Yang Tae-Young, who captured the bronze.

Paul Hamm plans to keep the gold medal, but will travel to Switzerland this month for a hearing regarding the medal.
