Toilet Seat

A man decides to take the opportunity while his wife is away to paint the wooden toilet seat.
The wife comes home sooner than expected, sits, and gets the seat stuck to her rear. She is understandably distraught about this and asks her husband to drive her to the doctor.
She puts on a large overcoat so as to cover the stuck seat, and they go.
When they get to the doctor's, the man lifts his wife's coat to show their predicament. The man asks, "Doctor, have you ever seen anything like this before?"
"Well, yes," the doctor replies, "but never framed."

Andrey Andreyevich Markov

Died 20 Jul 1922 at age 66 (born 14 Jun 1856).Russian mathematician who helped to develop the theory of stochastic processes, especially those called Markov chains, sequences of random variables in which the future variable is determined by the present variable but is independent of the way in which the present state arose from its predecessors. (For example, the probability of winning at the game of Monopoly can be determined using Markov chains.) His work based on the study of the probability of mutually dependent events has been developed and widely applied to the biological and social sciences.
