In the past I have done: sporting event tickets, a new jacket, a little something for camping, lotter tickets, his favorite beer.
I usually always make dinner. We used to go out to dinner before the kids until one year when it was just such a long wait for the table, food & difficult service due to the amount of people dining (not the servers fault) and we decided not to do it again.
Think of your mate and get him what he enjoys most: food, snacks, tv time, his favorite beer etc. and sit down to watch tv with I'm.

I'll make a nice dinner with all of his favorites for all of us to enjoy at home (filet mignon or tri-tip), get him his favorite beer, buy a nice dessert, let him have the tv all night. That's about it. We don't exchange gifts anymore. We'd rather spend our money on other things.
