The less I drink, the more drunk I get

On the lighter side:

A beer addict orders 5 glasses of beer. He gulped it down. Then he ordered 4 glasses, and gulped it down. He ordered 3 glasses and gulped it down. Then he ordered 2 glasses.

The bar tender said, "I have never seen a customer drink beer in this manner. It's surprising." The addict said, "Yes. I am also surprised. It seems that the less beer I drink, the more drunk I get."

Larry Haverkamp said, "The beer addict is focusing on the first derivative and not on the absolute quantum". Can you understand Larry?
