Fans aren't the only ones sharing their Olympic delight on the Internet.... the Olympians themselves are getting in on the action. Team USA Olympic Swim Team took a break from their Olympic training to take on Carly Rae Jepsen's Call Me Maybe.

The proud papa added the caption: "Thomas has some Olympic pride :) GO USA!!!!"

Is Thomas the cutest little USA fan or what?
