With the season coming to a close, the networks are starting to look toward next season. In the case of 'Criminal Minds,' that includes exploring the possibility of a spin-off series. They ran an embedded pilot for it earlier this season, introducing the new cast, and they've already had tremendous success with both 'NCIS' and 'CSI' spin-offs. But whatever happened to the old-school way of creating spin-offs?

'Frasier' was a long-time cast member on 'Cheers' before he headed off to Seattle and sitcom super-stardom. 'The Jeffersons' spent time living next to the Bunkers ('All in the Family') before moving on up. Even as recently as 'Friends,' they spun series co-star 'Joey' off into his own series -- maybe that's when it all went so wrong.

So what's a second banana? Well they're certainly not second best. No, in fact they're often the main reason to tune into a particular show. Not because the show's major plotlines revolve around them, in fact they generally don't, but because they liven up every scene they're in. Virtual show-stealers, a good second banana can turn a generic sitcom or drama into television gold. The ultimate wingman on television, there was no greater second banana than my man Barney Fife, brilliantly played by Don Knotts on The Andy Griffith Show, and later Mayberry R.F.D.

When it came time to put together this list, I wondered if I'd be able to find ten viable and qualified bananas on the airwaves today. But I guess I needn't have worried. It looks like Barney was an inspiration (in more ways than one) to the current crop of second bananas. They litter their peels all over the television landscape, leaving us to trip over in laughter time and time again at their antics. But how do they stack up? Who's the biggest fruit in the tree? There's only one way to find out!
