So the father is up the ladder sawing a branch and the son is standing under the branch!
Father: I think you better move.
Son: what! Do you think I'm stupid?
Father: saws through the branch.
Son: d'oh!

I can not tell you the number of times I've heard the son say
"what! Do you think I'm stupid?"

Oh, by the way, YES.

Stochastic

Stochastic (from the Greek στόχος for aim or guess) means random. A stochastic process is one whose behavior is non-deterministic, in that a system's subsequent state is determined both by the process's predictable actions and by a random element. However, according to M. Kac^[1] and E. Nelson^[2], any kind of time development (be it deterministic or essentially probabilistic) which is analyzable in terms of probability deserves the name of stochastic
