I think it's cute and illustrates a lot of D's features at 
compile time.

void main()
{
   static if (__DATE__[0..6] == "Dec 08")
   {
     pragma(msg, "Happy Birthday to You");
     pragma(msg, "Happy Birthday to You");
     pragma(msg, "Happy Birthday Dlang");
     pragma(msg, "Happy Birthday to You\n");
     pragma(msg, "  D programming language is ",
       mixin(__DATE__[7..11]) - 2001, " years old!");
   }
}
