Steve Martin has a way with words

From Steve Martin - Comedy Is Not Pretty!

The long buildup stretches out the tension. This joke could be told in 10 seconds but it's the stretch that gives it tension and gives away the persona of the narrator. Interesting: The punchline is actually silence. The pause is when you realize the true message being conveyed is the complete opposite of the words being said. That incongruity is the laugh spark. Then you've got the smarmy tag "Oh, not have way I guess." Brilliant act-out that gives a final punch to it and shows the level of bullshit being dispensed.
