No matter how advanced our computer games get, board games will never go out of style. There's something about just sitting around, being ridiculously competitive with family and friends that brings out the most laughter. My personal favorites are Taboo and Cranium.
Price: From $10 - $50
Alternatives: For something a little more complicated, try Risk or Monopoly Deal. For something easy and fast, try Jenga!
That being said, the technology in games these days is very impressive. I hear Skyrim is the cracktastic game to have this season?
Alternatives: Your gamer brother or sister will probably know better than me.
And after all that horsing around, if your friend is still bored, it's time to get serious. Get them a reservation for bungee jumping, skydiving, whitewater rafting, canyoneering, paragliding, and more! I'm only familiar with a few places in California, but I'm sure they're readily available everywhere. Just make sure it's reputable and safe!
Price: Starting at $80
After that, it's time to remind them that things could be much worse with the famous drinking bird.
Alternative: TV (Link is to King-Size Homer episode with the drinking bird)
