An eagle was sitting on a tree...
An eagle was sitting on a tree resting, doing nothing.
A small rabbit saw the eagle and asked him, 'Can I also sit like you and do nothing?'The eagle answered: 'Sure, why not.'
So, the rabbit sat on the ground below the eagle and rested. All of a sudden, a fox appeared, jumped on the rabbit and ate it.
Moral of the story:
To be sitting and doing nothing, you must be sitting very, very high up.

First airplane stamp designIn 1913, the world's first stamp to depict an airplane (a biplane) went on sale at U.S. Post Offices. (It was issued two weeks earlier, on 16 Dec 1912, six years prior to the first U.S. airmail stamps.) It was a 20-cent Parcel Post stamp, with carmine rose red ink, titled “Aeroplane Carrying Mail,”part of a series of 12 stamps for use on parcel post. On 24 Aug 1912, Congress had authorized the U.S. Post Office to enter the parcel post business to improve service for rural areas poorly served by private delivery companies. Four stamps in the series showed workers (including 3c. "Railway Postal Clerk," 4c. "Rural Carrier" in a horse-drawn wagon). Four more had transportation methods (including a 5c. "Mail Train," 10c. "Steamship and Mail Tender," 15c."Automobile Service"), and others showed industries.« |
