The Imperials are in the Death Star celebrating Darth Vader's Birthday. One of the officers was singing "Happy brithday to you. You belong in a zoo. You look like a monkey, aaaaand you smell like... one... too- oo?" However, everyone else had finished singing when he was on his last line, so Vader heard "You look like a monkey, aaaaand you smell like... one... too- oo?" Vader began force-choking the officer, saying' "I find your lack of faith disturbing." Grand Moff Tarkin said to Vader, "enough of this. Vader, release him." Vader did release him... by throwing him against a wall and killing him.
