A wealthy, English, Jewish guy buys a fabulous home with over 50 rooms. He brings in a local workman to decorate the place. When the job is finished the Jewish guy is delighted but realizes that he's forgotten something - to put mezzuzos on the doors. He goes out and buys 50 mezzuzos and asks the decorator to place them on the right hand side of each door apart from bathrooms. He's really worried that the decorator will chip the paintwork or won't put them up correctly, however, when he comes back a few hours later the job has been carried out to his entire satisfaction. He's so pleased that he gives the decorator a bonus.
As the decorator is walking out of the door he says to the Jewish guy: "Glad you're happy with the job mate. By the way, I took out all the guarantees that were in the little boxes and left them on the table for you Happy New Year
