Humor is subjective. What you find funny won't necessarily be the same thing even your best friend finds funny. So in order to know what tickles his funny bone, get to know him! What TV shows does he like? What comedians? What kind of humor does he use to amuse others? All of these are cues as to what gets him giggling. The most aptly-timed joke on, say, Foucault won't be appreciated by the type of guy who prefers laughing at toilet humor. And it works the other way around, too. Does the guy you're eyeing prefer bro banter? Is he into witty non-sequiturs about current events? Can he be slayed by a play on words in Klingon? Find out! On the whole, women value a sense of humor more than men do. What do men want? Someone who will make them feel funny. Instead of trying to impress him, show him that he impresses you. Showing him that he has the right to laugh at his own jokes, too, because he's just so darn awesome could win him over in no time. You don't have to laugh at every joke he makes like your world has just been altered. If he drops a dud, laugh at him, albeit playfully. Did he just try an unfunny, stereotypical, sexist, blonde joke? Oh, honey. Let him know how cute he is for trying with a fake chuckle and a forced grin. When we click with people, chemistry is pretty Unable to ignore. To show him that you just get him and that you appreciate his humor, feed off of it! Did he just whip out his Sean Connery impression on a dime? Keep it going with your best Alex Trebek or Pussy Galore (doesn't have to be good -- this moment is about him). If not an impression, can you drop a line from a movie or challenge him to up his game to Christopher Walken? Establishing a banter can develop a rapport between you two, creating a bond that won't easily be broken. Whether his humor is self-deprecating or straight out of Family Guy, go with it. Show him that you appreciate how fun he is.
Get to know him. Laugh at his jokes. Feed off his humor.
