Jon Stewart returns to his "Daily Show" perch tonight after a summer in Jordan, and although he's only been gone for 3 months, it seems like much longer. After all, he's been the closest thing we have to a voice of reason across the media landscape for the last nearly 15 years.
That's right: 15 years. Check out the video above to see a montage of Stewart's evolution throughout his reign on the show, which he took over from Craig Kilborn before the 2000 presidential election. Watch his astounding transformation from a short, sardonic, jet-black haired jokester to a short, sardonic gray haired jokester.
