Fun basement and backyard entertainment

[wacki]

Creating a list of games/sources of entertainment that would be fun to have either in the basement or in the backyard for when a dozen or two beer drinkin guests come over. Looking for game setups that could be bought or built for 5K or less and force people to interact with others. But mainly I've been going to a lot of campfires lately and have had a lot of fun and met a lot of people playing cornhole and similar random and cheap backyard games which has caused me to wonder what else is out there.

<ul type="square">[*]Caribbean Ring Toss (wallhooky)[*]Cornhole[*]A football themed game with two 1" diameter foam footballs connected with a string that you throw at a football post trying to wrap it like a boa. I have no idea what it's called but it was a lot of fun to play.[/list]Then your more typical:
