She turned into a lion when making love.

Everyone likes a good laugh, especially when someone else is in on the joke.
And when it comes to romantic connection, laughing can really seal the deal, according to three recent studies done by the same researcher
In “Sexual Selection and Humor in Courtship: A Case for Warmth and Extroversion,” Jeffrey Hall, Ph.D., associate professor of communication studies at the University of Kansas, studied that very topic.
Hall concluded that when strangers meet, the more times a man tries to be funny and the more times a woman laughs at those attempts, the more likely it is for the woman to be interested in dating.
An even better indicator of attraction is if the two are seen laughing together.
“The studies I set out to do were intended to look at a theory that’s out there that says when men make jokes they are trying to advertise something about themselves, so by being funny they’re trying to advertise their intelligence. In other words, humor is a good sign of a good brain or intelligence,” Hall told Healthline.
