Why is this interesting? I accept that it is an example of a recursive function, but I don't see why is deserves an article. And why is it restricted to positive integers? --Henrygb 12:30, 10 Aug 2004 (UTC)

It's interesting because it is. Also, because this function is hilarious.

Here's a function that Henrygb might find interesting. It returns 91 for all input, not just positive integers:

D(x) = 91

What was McCarthy's original motivation for this function? A simple illustration of recursion? --Bubba73 14:18, 27 May 2005 (UTC)[reply]
