Mulla Nasrudin rushed into a bar and said breathlessly, “The usual, please, and hurry, I gotta catch my train.” The bartender set up five martinis in a row and the Mulla gulped the second, third and fourth, leaving the first and last drinks on the bar. Then he rushed out as rapidly as he had entered. A bystander asked the bartender why the customer left the two drinks.
“Oh, he does that all the time,” said the bartender. “He says the first one always tastes terrible and the last one gets him in trouble at home.”
