Have a good quant joke? Share it here. The principle "should be of interest to quants" trumps.

I would be particularly keen to learn jokes which involve some nontrivial finance/mathematics. I am looking for jokes which make you laugh and think at the same time.

This is a community wiki question: One quant joke or pun per answer please.

Efficient Market Hypothesis Joke:

"There is an old joke, widely told among economists, about an economist strolling down the street with a companion when they come upon a 100 dollar bill lying on the ground. As the companion reaches down to pick it up, the economist says ‘Don’t bother — if it were a real 100 dollar bill, someone would have already picked it up’.”

Adapted from a joke about economists:

A quant(financial engineer), a mechanical engineer, and a chemical engineer are shipwrecked on a deserted island. They are starving, and are tired of eating coconuts. They come upon a can of food on the beach....

The mechanical engineer says, 'let's wdge the can between these 2 palm trees and rig a branch to chop the top of the can off' The other two quickly point out that this will destroy the can and likely send the contents all over the place, wasting them...

The chemical engineer says, 'let's take the sea water and reverse the polarity of the water extracting the salt to make an acid and then burn one end of the can off' The other two quickly point out that while this is clever it will likely ruin the contents of the can.

The quant says, 'let's make a simplifying modeling assumption.... let's begin by assuming that we have a can opener'

Investment bank Dog competition:

A researcher, a risk manager and a trader each bring a dog to a competition.

The first one to display is the researcher's dog. The researcher brought a bottle of milk a bowl and placed it all on the floor. Then he commanded the dog to take the bottle and pour the milk into the bowl until the maximum amount it could hold. And that is exactly what his dog did.

The second one to display is the risk manager's dog. The risk manager's brought a bottle of milk a bowl and placed it all on the floor. Then he commanded the dog to take the bottle and pour the milk into the bowl until two thirds of the maximum it could hold and without spilling any milk during the whole process. And that is exactly what his dog did.

The third one to display is the trader's dog. The trader did not bring anything other than the dog. Then he commanded the dog to do what he taught. The dog stands up and walks in the direction of each one of the bowls and drinks all the milk.
