Bart has his ear pierced and gets an ear-ring but Homer confiscates it.Later Homer and some colleagues join the Naval Reserve and sail on a submarine,where Homer accidentally fires the captain out of the torpedo hatch and,left in charge,allows the sub to drift inti enemy waters. It is attacked and springs a leak but Homer saves the day by sealing it with Bart's ear-ring before returning home for a dishonorable discharge.
