Yahoo recently conducted a survey to determine the greatest TV theme song of all time. They did it in one of those March Madness-style brackets, and this year's Louisville of theme songs was . . . 'Gilligan's Island.'

They started with 32 shows, and the other three in the 'Final Four' were: 'Cheers,' 'M*A*S*H' and 'The Jefferson's.'

Some of the other themes that were featured include: 'Laverne & Shirley,' 'The Andy Griffith Show,' 'The Fresh Prince of Bel-Air,' 'The Monkees,' 'The Golden Girls,' 'The Simpsons,' 'Three's Company' and 'The Mary Tyler Moore Show.'

What tops your list of the best TV theme song?
