Hi, @adisrivastav
Thanks for letting us know about that, but actually Cheetah is wrong because the joke we used was from here: http://jokeindex.com/Joke.asp?Joke=4092 and we made some adaptations to the text (as we usually do off course) and used clipart ( Creative Commons Zero 1.0 Public Domain License)
In fact our project, as well as our popular instagram is about that: https://www.instagram.com/bestwebjokes/ and soon we will be launching a website as well as publishing an online book.
We find great jokes we like and we think are funny, and we make adaptations to text (some stories more, other less depending on the joke) and we use funny and nice clipart relevant to the joke. In fact most of the posts here will be published in the future ebook.
Thank you for your message,
@bestjokes
