31. Hawkeye Pierce and BJ Hunnicut, 'M*A*S*H'
When merry prankster Trapper John McIntyre left the 4077th behind due to creative differences — sorry, a transfer back to the States — his longtime partner Hawkeye Pierce needed a new foil. Along came B.J. Hunnicutt (Mike Farrell), a laid-back Californian who made an even better partner for Alan Alda's iconic Army surgeon. Their friendship formed the backbone of eight of the long-running Korean War comedy's 11 seasons, and their comedic and dramatic interplay was unmatched on the show.
