This video shows over 30 different varieties, from the typical “clapper” to the disturbing “contagion.” Chances are that you’ll probably recognize your own laugh in the video, or, if you’re like me, you’ll see a few different laughs that you use depending on the situation or joke involved. While you’re watching, you’ll probably also notice some of the incredibly annoying forms of laughter and while it’s good to be able to crack up without feeling self-conscious, if you’re a “mimer,” “baby waker” or use a “no-smile,” you might want to see if you could make your laugh a little less irritating to everyone else.
