I don't know if this is really a joke. It is certainly not easy to answer
`?`(`?`(`?`(`?`(`?`))))
and spending some time trying to contact Delphi (maybe in order to
permit cosmic radiation to feed the solution into the computer's RAM) is
possibly one of the most promising approaches ;-)

Hello,
In R 2.10, looking at:

else {

I am especially puzzled by this part:
cat("Contacting Delphi...")
flush.console()
Sys.sleep(2 + rpois(1, 2))
cat("the oracle is unavailable.\nWe apologize for any inconvenience.\n")
We now got jokes in R code? Why not? ;-)
Best,
Philippe
