hiding strings in binaries

I didn't write this program and I don't know how it works.  It was posted 
on the nyx freenet by kstern at nyx.cs.du.edu.  When you compile and run it, 
it prints out the lyrics to "The Twelve Days of Christmas".  As you might 
imagine from looking at the code, strings doesn't find anything in it.



#include <stdio.h>
main(t,_,a)
char *a;
{
return!0<t?t<3?main(-79,-13,a+main(-87,1-_,main(-86,0,a+1)+a)):
1,t<_?main(t+1,_,a):3,main(-94,-27+t,a)&&t==2?_<13?
main(2,_+1,"%s %d %d\n"):9:16:t<0?t<-72?main(_,t,
