Smalltalk, Haskell, and Lisp

...walk into a bar.

Smalltalk: “Bartender, please send an instance of Martini to me - selector withOlive: set to true.”

Haskell: “I’ll take beer >>= chill, but only if it’s defined for all inputs and returns IO ().”

Lisp: “(drink ’(ale (temperature cold))) .”

The bartender mutters, “Great ... an object, a functor, and a list.”

Then a janitor walks by sweeping the closures that they left.
