basically: add a TV, some junk food, alcohol, and your choice of drugs.
easy fun is when you're not actually doing anything but you're having fun because of the obvious funn-ness of what you're doing.
you could be doing the same thing every weekend and it would still continue to be fun, just because it is.
be careful, though: those who get used to easy fun will, over time, not be able to have fun any other way.
i had easy fun last weekend. i went over to my friends house and we smoked 15 joints and drank some vodka, then watched alice in wonderland three times and passed out. in the morning, we had a wake-n-bake. i'm gonna do the same thing next weekend even though I just got invited to a grammy awards party and they were gonna give me free chanel perfume. that just doesn't sound very fun.
