One story from that article:
Jamie Farr (Klinger) remembers Stiers and Farrell being the biggest pranksters. "They were the culprits." If you polled castmembers about the greatest joke played during the series run, they would all say without hesitation: "Attenborough."
During the 1977-78 season, Richard Attenborough took residence on the 20th Century Fox lot to direct Magic, a twisted horror film starring Anthony Hopkins and Ann-Margret. Many of the people working on the lot, including Attenborough, often frequented the commissary for lunch. One day, Morgan, Farr, William Christopher (Father Mulcahy), Farrell and a crewmember went to the commissary and situated themselves in a booth for lunch. As it would turn out, Attenborough was across the room with some people, also enjoying a meal.
"As we were finishing our meal, this line of waiters came up to us with a flourish. They had soft-serve yogurt — at the time a fancy new dessert in the commissary — brought to us and served in goblets. The waiters made a big deal out of it, setting it down in front of each of us. They said, 'Compliments of Sir Richard Attenborough,'" Farrell recalls. "We were blown away that Richard would know who we were, let alone treat us to this fabulous dessert. So, we turned and waved graciously and said, 'Thank you, Sir Richard, so kind of you.' We had to call it out a little bit because he was across the room. Attenborough didn't even turn to acknowledge us. So, we said it louder. Again, he ignored us. Then Harry stands up and yells, 'Thank you, Dickie.' Nothing. I was trying to figure out what was going on. My eyes sweep the room and I see, over in another corner of the commissary, David laughing to all hell. And I thought, 'Oh, that son of a bitch.'
"I said to the guys, who were still standing, 'Stop. Hold it, I think we've been had here,'" Farrell continues. "Stiers is over there having a spasm. He's having so much fun at our expense. When the waiter comes over with the check, it includes the desserts on it. I figure we can't let David do this without some consequence. So, I tell him to take the entire check to Stiers. I watched as the waiter hands David the check. He looks at it, signs it with a flourish and walks out. I ran out after him and caught him in the street and I said, 'David, I didn't really mean for you to have to pay for our meals. I just wanted to get back at you in some small way for humiliating us, you son of a bitch!' And David says, 'Oh, it's alright Mike, I signed Gary Burghoff's [who played 'Radar' O'Reilly] name to it."
