yeah dude, or, instead of kicking him to the curb.....kick his ass and then while he's on the ground explain to him exactly why you did it, it should get your point across and if he's a true friend he will see it through your eyes and really see what he has been doing. trust me, some people just need a good ass kicking sometimes and this might just possibly be one of those times.
after you beat the shit out of him, be sure to get a lot of alchohol and get him drunk and stoned. then you can laugh about it.
