here's the content of a SO deletion by a sanctimonius obstructionist.
I think I've seen an Easter egg or two in some R packages, but I am not able to recall them. Here are a few from Matlab, and more here, if you want to see some examples of Easter eggs. Are there any known Easter eggs in R or some of the major packages? (If justification is really necessary...the reason for asking is simple: some of the Easter eggs for Matlab demonstrate useful functionality and happen to be amusing. I'm not particularly enamored with their "default image" Easter egg, but the examples for simulations (e.g. life and toilet) are actually useful for code and pedagogical purposes. Not all demos need to be dry.)
