What is the output?

/* From "C for Dummies, Volume One" */

#include <stdio.h>

void jerk ( int repeat );

int main ( void )
{

  printf( "He calls me on the phone with nothing to say!\n" );
  printf( "Not once, or twice, but three times a day!\n" );
  jerk( 1 );

  printf( "He insulted my wife, my cat, my mother!\n" );
  printf( "He irritates and grates, like no other!\n" );
  jerk( 2 );

  printf( "He chuckles it off, his big belly a-heavin'!\n" );
  printf( "But he won't be laughing when I get even! \n" );
  jerk( 3 );

  return 0;

}

/* The jerk function repeats the refrain for the value of the repeat 
   variable */

void jerk( int repeat )
{

  int i;
  
  for( i = 0; i < repeat; i++ )
    {
      printf( "    Bubba is a jerk!\n" );

    }

  printf( "\n" );
}
