You are SO right on! I remember when the entire cast came on stage and announced their replacements for the upcoming season. I thought it was a joke as they are always kidding around. I was so depressed to learn they were telling the truth.
My brother is a complete TRIP. He also used to call my secretary and say it was Clark Griswold calling (Chevy Chase from the Vacation movies). My secretary was so naive and professional, she used to ring me up and say "there is a Mr. Griswold on the line". My brother would just roll on the floor laughing.
