How to force laughter

I remember learning how to force a laugh. 

The first part of that lesson is to determine when a forced laugh is appropriate. It's something you can actually practice by yourself. If you see something during your day that seems a little funny, but not really, you can vocalize an exasperated nose snort into a nasalized "hmpf."  Start doing this often. Soon, you'll be opening your mouth a little, and trilling your vocal chords, working up the a cautious laugh, the progenitor of the fake laugh. 

With this technique firmly established, you now need to take it into the public sphere. The best place is away from friends, because strangers often need to be laughed with.  You will note that many of these strangers will themselves be fake laughing around what is known in social media as "an influencer".  An influencer can laugh about anything, usually, animals' or other peoples' misfortunes. They especially enjoy a laugh when they are the witting cause of this misfortune. 

So as you can see, a fake laugh is easy to practice as a complement to an evil laugh. As you express your fake assent for the miserable state of the world, you can at least enjoy a drink or two for a few hours. I know I did.
