10. Matt Le Blanc in Joey (2004-2006) and Episodes (2011-)
This short-lived series is proof you can't stretch 'How you doin'?' to last 22-24 minutes. As much as we loved Joey on Friends, he worked best as part of an ensemble. It just felt weird watching him without the others. It might have helped if the series was actually funny, or if the other characters were remotely interesting. But to be fair, his latest series Episodes is pretty awesome. He plays a spoof version of himself!
