For Dr. William Jefferys
Shall I introduce you to Bayes?
His inferences always amaze.
It's not what you think—
without a stiff drink—
But it will end your frequentist phase.
No, really, it is what you think
—unless to you orange is pink.
For without a good prior
You'll never get hired
And maybe should find a good shrink.
If Bayesian stats make you cuss,
Or your Bayesian book you did toss,
Please don't give up hope:
If you really can't cope,
Just try this new book by Laplace.
