According to a recent study, when it comes to attraction, women are genetically wired to fall for men who can make them laugh. Forget chiselled looks or highbrow intellect – there is more than just the appreciation of a good joke that makes a funny guy so hot. A naturally funny man will, not only be able to deliver a cracking one-liner, but will also demonstrate the seductive ability to laugh at himself.
Unlike your classically good-looking-with-not-much-up-top breed of man, a funny guy knows he’s not perfect but uses his imperfections to reel you in, turning his insecurities into weapons of mass seduction to blow you away.
