Well, I can't say I'm qualified to say whether or not he truly deserves that appellation, not when Paul McCartney's still around...but I'm also not prepared to say definitively that he doesn't. Goodness knows he's a personal hero of mine, as I have been known to loudly proclaim with a considerable overabundance of vehemence, ignorant of the fact that Melinda Gebbie, his wife and sometime co-creator, was four feet away at the time. (And then loudly telling the story of my stupiditity the next night...unaware that the reason everyone was smiling was because she was standing right behind me. Yes, really.)
Either way, this screengrab cracks me up.
