One humorous adult joke says, "Your mama is so classless, she could be a Marxist utopia." This joke requires a knowledge of politics. The joke plays on the fact that Marxist utopias do not have social classes.
As most people get older, their senses of humor become more sophisticated and they understand complicated jokes, the American Psychological Association says.
An example of a clever grammar joke for adults is, "Knock, knock. Who’s there? To. To who? No, to whom." One that requires a knowledge of Beethoven's ninth symphony goes, "What was Beethoven’s favorite fruit? BA-NA-NA-NAAAAAA!"
Another joke for adults that requires some knowledge of music says, "A sign at a music shop: 'Gone Chopin. Bach in a minuet.'"
One joke story that pokes fun at growing older says, "Seeing her friend Sally wearing a new locket, Meg asks if there is a memento of some sort inside. 'Yes,' says Sally, 'A lock of my husband’s hair.' Meg says, 'But Larry’s still alive.' Sally responds, 'I know, but his hair is gone.'"
Religious jokes for adults include a story of a man speaking to God, which states, "A man is talking to God. 'God, how long is a million years?' God answers, 'To me, it’s about a minute.' The man asks, 'God, how much is a million dollars?' God answers, 'To me, it’s a penny.' The man asks, 'God, may I have a penny?' God answers, 'Wait a minute.'"
