Wait, maybe the user is referring to a specific instance where Mr. Bean, in a holiday episode, says something that sounds like "I Said Dub." Let me recall Mr. Bean episodes. There was a "Mr. Bean's Holiday" movie (2007), but the user might be thinking of an episode. There are a couple of holiday-themed episodes in the original series, like "Mr. Bean's Christmas" (1990) and "Mr. Bean in New York" (1993). Maybe in one of these episodes, there's a scene where Bean encounters a situation where he mishears or someone mishears him, leading to "I Said Dub."
