Want to bond with a new group of people? You could cover all your clothing in glue, or, if you're on a budget, you could just laugh with them. If you've ever been the only person in a group who didn't get a joke, you probably already know that laughter is critically important to successful social interactions. Scientists have found that mutual laughter helps people feel at ease around each other, and laughing when others are laughing makes those others more likely to accept you into their group.

1. Think of something you find funny. Not surprisingly, the easiest way to laugh is to think of something that you personally find very amusing. It seems a no-brainer, but it can be useful for those occasions where everybody but you is laughing at a joke. Why would you want to laugh just because others are laughing? Laughing along with one or more people shows them t have to amuse yourself.
2. Smile . If you do want to fake... er, create a laugh, start with a smile. Scientists have found that genuine laughter is almost accompanied by the contraction of about 15 facial muscles, most of which are the same you use when you smile. Remember to smile with your eyes as well as your mouth. Smiling not only is a part of the natural laugh reflex; it can actually put you in a better mood and make you more apt to laugh.
3. Match your vowels. A typical laugh consists of short vocalizations, each with the same vowel sound. So, for example, "ha ha ha" will sound like a normal laugh, as will "bo ho ho," but "ha ho ha" just sounds weird. And kind of scary.
4. Taper your laugh. The typical laugh starts relatively loud and then tapers gradually off. While this isn't always the case, laughs that increase in volume or that stop abruptly are generally suspicious.
