Please, tell him first about random streams, which he can handle without IO. Or, about ergodic functions (hashing contraptions which transform ANY parameter into something unrecognizable). When he says : "I know all that", THEN hurt him badly with monads.

i think that for someone coming from imperative programming teeling about IO monad is the easiest way. and then he will learn how to do it FP way

I came from imperative programming and never wanted to use randomIO, because it forces you to IO and randomsIO is not lazy.
