Leno is one guy I cannot tolerate. Kisses a$$ bigtime to guests when they are on the show, then stabs 'em in the back when they're not. Anything, and I mean anything, just to get a laugh.
Worthless is the only word I can think of to describe him.
He's not worthy of shining Johnny Carsons shoes, IMHO.
I can't watch late night talk shows anymore. They have gotten incredibly boring. Usually the guests are self-important celebs who are there mainly to plug their latest projects. Once upon a time, late night talk shows were actually quite interesting to watch and the guests actually engaged in REAL CONVERSATIONS. They had a documentary about Jack Paar and it was fascinating to watch how interesting the guests, such as Jonathan Winters, Oscar Levant, and even a spaced out Judy Garland were. And, of course there is that time on the Johnny Carson show where a tipsy Dean Martin tapped ashes from his cigarette into an unsuspecting George Gobel's drink.
Nowadays the guests are usually much too pompous to engage in playful banter and too stupid to carry on an intelligent conversation. It's all about plugging their careers.
