This is part of the complete Exercises in Song cycle being released on this site.
"Probabilistic " is a bonus exercise, not to be found in Raymond Queneau's original Exercices de Style nor in the translations.
To be sung to the tune of "Show Me The Way To Go Home". More information here.
Odds that one's wishes for rest
And places to rest in coincide,
Where sleepiness is caused by drinking far from one's house—
Such a chance, in truth, is slight.
I make it one in three
That I'll find land, foam or sea.
But your list'ning to this song is, by now,
Something of a certainty!
