George Clooney [1] stopped by Jimmy Kimmel Live [2] on Monday night to chat about his new movie Suburbicon [3], but as it usually happens with new parents, the conversation quickly turned to the actor's kids. George welcomed twins Ella and Alexander [4] with his wife, Amal [5], in June, and asked Jimmy's audience if they wanted him to bring the little ones out to make their TV debut. After the crowd excitedly cheered, Matt Damon [6], aka George and Amal's "Manny," walked out pushing two strollers. "So, based on your physique, I guess your breastfeeding the children, too?" the host teased his longtime frenemy [7]. Matt then had the last laugh when he went to reveal the kids, only to pull out his two middle fingers. "There they are — right there," he said. "This is Screw and this is You." Oh, boys. We love this immature and hilarious bickering way too much.
