During a visit to the mental asylum, a visitor asked the Director how do you determine whether or not a patient should be institutionalised.
Well, said the Director, we fill up a bathtub, then we offer a teaspoon, a teacup and a bucket to the patient and ask him or her to empty the bathtub.
Oh, I understand, said the visitor.
A normal person would use the bucket because it's bigger than the spoon or the teacup.
No said the Director, A normal person would pull the plug out.
Do you want a bed near the window?

Cable car

In 1871, a U.S. patent was issued for an “endless wire rope way”subsequently used for the first cable car to be put into service in the world for public transport (No.110,971). The invention by Andrew S. Hallidie began service in San Francisco on 1 Aug 1873 on Clay Street Hill. It ran from Kearny Street to the crest of the hill, a distance of 2,800 feet, making a rise of 307 feet, and moved by motor-driven cables under the city street. [An earlier cable car patent was issued for an “improvement in tracks for city railways,”being an underground tunnel having a series of pulleys inside housing the cable. That inventor, Eleazer A. Gardner of Philadelphia, Pa. received his patent (No. 19,736) on 23 Mar 1858.]
