“It's very dry.”

Your brother tells jokes without laughing, so you can never tell whether he's joking. You're talking about him with your daughter, and she says, "He has a weird sense of humor." You agree, and you want to describe his sense of humor more specifically. You say:

It's very dry.

a dry sense of humor

If someone has a "dry" sense of humor, it means that they make jokes or say funny things quietly, without directly showing that they're joking. A person with a dry sense of humor usually doesn't smile or change their voice much when they're joking. It's almost like they're hiding the joke so that only smart people and careful listeners will get it. British people are often thought of as having a "dry" sense of humor. Here are some other ways that people can be funny:

• If you have a dirty sense of humor, it means that you tell jokes about sex.
• Absurd humor is when people do things that are ridiculous and don't make sense.
• Slapstick humor is something that you mostly see only on TV, movies, and in plays. This is when someone gets hurt, drops things, falls down, etc. It's also called physical humor.
