I distinctly remember Lou Holtz telling this joke, which is classic today.
Sam Lapides (that was his character that he used), Sam Lapides goes to the grocery store to buy some salt. He goes to the grocer and he says to the grocer, “Have you got, do you have salt?”
And the man says, “Have I got salt? Have I got salt? Here, take a look this wall. Salt, salt. Take a look down here. Salt, salt. Take a look here. Barrels salt, boxes salt. Come on downstairs. I show you more salt. That kind of salt. We have salt here. And where else? Salt. Salt. My God.”
And Sam Lapides says, “This is marvelous, but will you ever sell all this salt?”
And the grocer he says, the grocer says, “Me? I can’t sell salt, but the guy who sells me salt, OH can he sell salt.”
