The Venturi brothers get one within five minutes of each other. First, Edwin raids the graduation ceremony, putting the principal (and everyone else with a shred of authority) on notice that they're STILL in for more Venturi hijinks - and then... Derek's appearance on stage to receive his diploma. Classic.
Derek telling off Casey's boyfriend Truman and her cousin Vikki after Casey sees them making out. Derek also becomes concerned and sincere towards Casey when he sees her crying. Watch here.
