My joke generator got a complaint about getting lost in all the map transforms, so in an effort to make my code easier to follow (ahem) I have limited myself to only four occurrances of map in this little project, instead using the trinary operator, a lot of conditionals and comparisons, and far too many variables for such a short program. Enjoy :-)

Oh, you can take out the sleep 1 for hyper speed, if desired, which is useful if you want to use the command-line argument to specify large numbers of fighters. 500 ninjas take too long to duke it out with the sleep statement in.
