Funny series blooper about Robert Young

There is a blooper of the show where William Conrad and Martin Sheen are ina set of a plane and Conrad looks over, sees a UFO on the film screen and asks (asks actually swearing) "What is that--Marcus Welby". Funny, I did not think the UFO looked a bit like Robert Young. :)

PS Find the blooper at youtube.com/watch?v=5vOTLpAwOts or go to youtube.com and type in: "Cannon"- William Conrad-Bloopers" .
