This shortcut gets a random fact (from randomfunfacts.com), insult (from randominsults.net), or joke (from randomfunnyjokes.com) and will play one of those three randomly via Siri's text to speech. It will also copy the text of the joke/insult/fact to the clipboard so you can share it if you want. There are some options for changing up the verbiage prior to the joke/insult/fact, and to use those at random too. The joke also has a nice little drum sting at the end.
