Past masters of more clever humor and actual conversation: the late Steve Allen, Johnny Carson, and Jack Parr. And dig Jack Parr's pocket handkerchief too while you're at it!
In our current era of stupid humor, based more on bodily noises, contrived pratfalls, and Macauley Culkin-esque "Agggghhhhh!!!" screams than anything else, it's worth pointing out that stylish men cultivate a quieter type of humor. It is wry, witty, informed, and clever. . . rather than stupid, puerile, and just plain gross. Be sure you know the difference, and work hard to cultivate the former while avoiding the latter in those efforts to kick up your everyday style several notches. Remember, guys, you're not 10 years old anymore.
