Question: Which episode was Ian Thorpe, the Australian swimmer, in? — Liane R., Sydney, Australia

Televisionary: Jeez, Liane — you can't even tell me the name of the show you're asking about? Challenge me, why don't you? Well, I think I can help you anyway. I assume the series is Friends, because the Season Seven episode "The One with Ross's Library Book," which debuted Nov. 16, 2000, featured the Thorpedo as an extra in a Central Perk scene.
