I'm sure athletes get asked to act in all sorts of TV shows, but it's up to them to actually agree to do the show. So it was that a 20-year-old Roddick found himself making his TV debut on a tennis-themed episode of Sabrina the Teenage Witch back in 2002. It's important to note this happened years before both YouTube's fruition and Roddick's marriage to model Brooklyn Decker. Can't help but wonder if Roddick would do it all again, if given the choice.

Then again, this is a man who's expressed his unabashed love for the musical stylings of Rick Astley. Can't believe the Sabrina thing would be what he regrets.
