Gilbert Gottfried: Spoke to the Animals

A traveling salesman goes to a farm house. The farmer goes, I could put you up for one night, but youll have to stay in the barn. So he spends the night there and the next morning the farmer comes in, he goes, Were you comfortable? He goes, I had a great time; I talked to all the animals. He goes, You talked to the animals? He goes, Yeah I spoke to the chickens, they say you collect the eggs every morning exactly at five minutes after six. He goes, Thats exactly right. He says, The horse tells me his name is Otis, youve owned him for 10 years. He goes, Thats incredible.

Black American invention

In 1888, a U.S. patent was issued for the railway signal to the Black American inventor, A.B. Blackburn (No. 376,362). The type of signal was that designed to be operated by the wheels of a train. A lever was depressed as a train wheel travelled over it, to remotely operate an alert through a mechanical linkage upon the passing of the train. It was designed for use upon a single track railway line for trains passing in one direction. To provide a signal for trains passing in the opposite direction, a similar apparatus would be applied on the opposite rail. This patent was an improvement in mechanical design of his earlier patent No. 309,517 on 23 Dec 1884, in which he also described how a gong was activated to provide the alert.«[Image: detail from patent diagram showinf device beside a section of rail.]
