The other day a friend of mine shared with me the app Dad Jokes: The Best Puns by Jason Bryner. The app is very easy to use. As soon as you open the app a "Dad" joke will be presented to you. When you are ready for the punch line, simply tap on the screen. At the bottom you will see two faces (a smile and a straight face) - simply select what category you believe that joke lands in.
At the top of the screen are 3 dots that bring up the categories of Random, Best, Worst, and Most Controversial. Don't worry - the controversial ones are not controversial!
Embedded below is a 44 second YouTube tutorial.
