When the Sears Tower opened in 1973, Sears, Roebuck & Co. was the biggest retailing company in the world. The annual Sears Christmas catalog was like amphetamines for American schoolchildren. (This was before half of America’s schoolchildren were already on amphetamines.)
Sadly, as time passed, the fortunes of Sears & Roebuck declined. Sears moved its offices out of the tower and sold it to some guy named Willis, who was so sick and tired of listening to people say “What you talkin bout, Willis?” that he renamed it to the Willis Tower.
Now when people say “What you talkin bout, Willis?” he says “You want to know what I’m talkin bout?! I’m talkin bout THE TALLEST BUILDING IN NORTH AMERICA! That’s what I’m talkin bout, you pricks.”
