DeLorean gets in trouble.
(DeLorean walks over to someone who he thinks is Kumi)
DeLorean: Kumi, why do you look different?
Pelza: I don't look different and my name is not Kumi! It's Pelza! How dare you mistake me for Kumi? That's it! I will call your parents! Hi DeLorean's parents, your son mistook me for Kumi!
(at DeLorean's house)
DeLorean's dad: DeLorean, how dare you mistake Pelza for Kumi? That's it! You are grounded for 10 days!
DeLorean's mom: Go to your room now!
