Box of beer
In Vienna, a construction worker, Mr. Maier, falls from scaffolding and is fatally injured. Now the foreman complains: “Someone has to go to the old lady now and he says that her mother is never alive. He instructs the helper to deliver the message. After an hour he comes back with two crates of beer. The foreman: "You idiot, you shouldn't go to Billa for beer, you should go to the old lady Maier and tell her that she's never alive!"
The unskilled worker then says: “Yes, boss, I was with Mrs. Maier! I rang the bell and Mrs. Maier opens the door." "Yes, and continue," urges the policeman... "I say, 'Are you a widow Maier?'
