There are a lot of things in this wide world that are, at first appearance, terrifically unfunny. Large pores, for example. Large pores are terrifically unattractive and tremendously unfunny, which is why people pay huge amounts of money to luxury spas to have their pathetic bodies steamed and whacked with palm fronds and stuff like that. Mr. Bean has large pores. He lives with 'em.
Passport photos are funny.
So is Whistler's Mother, though how much fun she could be at a party is still open to debate. Bathrooms are funny. Beatles songs, God help us, are funnier the older they get. Bean gets good jollies out of all of the above, at least 3 times as much as he normally does on the Brit TV show on which the 90 minute movie Bean is based. The best part of it all is that very little of the gags that are in the movie are used in context in the television commercials.
