Vegeta: Because I can fight! Whereas he was banished and disowned by my father, because he's weak and a disgrace to the royal Saiyan name!
Tarble: Why do you hold a grudge? You have a nice son and wife, but you're always grumpy!
Vegeta: I'm not holding a grudge! Besides I'm your older brother. And according to most families, the older brother picks on the younger brother. >)
Trunks: This is getting kinda weird.
