A bummer we can't get the "passenger in the train car with Mr. Bean" pointing at the jackass and laughing at him. It's stuff like that which supposedly upsets the jackass of being ridiculed. He hates being laughed at in front of him.
I don't remember the name of the guy playing the character role [an entertaining rendition imo], but I recall reading he was a host of various UK shows in 1980s and 1990s.
