A live cat into a telephone...

In 1929 Professor Ernest Glen Wever and his research assistant Charles William Bray conducted a series of experiments using a live cat. They first sedated the cat and opened the skull to access the auditory nerve in order to attach it to a telephone wire that was connected to a telephone receiver. One scientist spoke to the cats ears while the other one listened through the receiver which was 50 feet was away in a soundproof room. They did various experiments using this poor cat which led them to win the first Howard Crosby Warren Medal of Society by the Society of Experimental Psychologists in 1936.

I will first explain why most of us usually wait until the day before deadline to do stuff.
