I am loving joke books currently-when I am on the train or just at home these books crack me up!
1) Laugh-Out-Loud Jokes for Kids
Yes its for kids, but these are solid one line jokes.
You can check out the book here
2) National Geographic Kids Just Joking: 300 Hilarious Jokes, Tricky Tongue Twisters, and Ridiculous Riddles
This takes me back to when I used to loving watching those specials with the African ladies!
Check it out here
3) Last but most certainly not least
Jokelopedia, Third Edition: The Biggest, Best, Silliest, Dumbest Joke Book Ever!
Who doesn't like dumb jokes??
