One Or Two Geese

A tailor's iron is called a 'goose'. A Kerry tailor wanted to buy two new irons, so he wrote away to the manufacturers as follows:
Dear Sir,
Please send me two gooses..........
After reading the letter he decided that this wouldn't do, so he changed it to Dear Sir, Please send me two geese............
However, he again felt that there was something wrong and that the manufacturers would be laughing at him. Finally he hit upon the following: Dear Sir, Please send me a goose.........
P.S. While you're at it, you may as well send me a second one.
