Noah Wyle
Alongside George Clooney was another ER hunk, Noah Wyle! He played another doctor in the same hospital as George, and he also managed to get a date with Monica Gellar. Does this hospital only hire the hottest medical professionals on the market?
Jon Lovitz
Seasons 1 and 9 boasted the guest star stylings of actor Jon Lovitz. Would you believe he played two different characters? Good thing audiences didn't notice. He played a high dinner guest in season 1 and a blind date gone wrong for Rachel in season 9.
