ELECTRIC dartboard!!!
Philistine! Blaspheme! 
The Mona Lisa of Guy’s room decorating is if you can get some of those life size standies of hot chicks that Coors gives to liquor stores. Most stores only keep them for a couple months then get rid of them, so ask if you can have it, but ask early cause dibs go early.
Pinball.
Real, live, big-mother pinball - with all the lights and bells.
No substitutes.
Extra points given for authentic solenoids-and-motors models, but the digital crap is acceptable.
Also, (heathen show hiss age) an old-fashioned trunk-style Coke machine - the lift the lid, slide a bottle through the slots, insert coin, lift bottle through the gate.
Mustn’t forget the Chair of Ultimate Power!!
Although an matching Couch would be nice as well.
Bikini girls.
Old bowling pins…from a junk shop, EBay, or just get a couple from the bowling alley. EVERY rec space has to have at least one old bowling pin in it. Bonus culture points for obtaining pins from rare bowling games such as Duckpins, Candlepins, Fivepins, etc.
How’s about a Nunzilla? Or just about anything from Archie Mcphee? Don’t forget enough storage space for your PS2 games. Do you have your own VCR in the room?
MY lair has, among other things, a HUGE 4’ x 6’ world map, dating from the 1940s, a crystal skull, a skeleton themed sand timer (must be seen to be believed!), some hand weights next to the computer, and several generations of game consoles. I’ve got some Furbies, as well, but you probably DON’T want those in your room.
A beer tap for the wet bar, and one of those hula-dancing dolls.
Bear-skin rug.
Christmas lights.
Black light posters & black light.
How about if I just describe my husband’s basement room, and you go from there? As mentioned before, there’s a urinal in the bathroom. He’s added Christmas lights around it, for a year-round festive touch. Mounted on the wall in the bathroom is a condom machine (theoretically, this is just for show, but I inventory the contents occasionally just to make sure…) Mounted OVER the urinal is a radio transmitter for an RC airplane. I have no idea why.
In the main room, there’s the big screen TV (satellite cable or whatever it’s called) with entertainment center, 2 couches and end tables, light-up beer signs, mini-fridge, stereo system hat makes the whole house shake, computer desk & computer, Nordic Track machine, ugly rug, WWII posters and memorabilia (a sign that says LIVE MINES, for example, although I think that one oughta go over the toilet, along with the gas mask he’s got over the computer), a gigantic light-up globe on a stand, a buncha bookshelves, wall-mounted bottle opener, industrial size garbage can, and a cigar humidor. He will be adding either a pool table or a skittles table, and he’s getting the dartboard for Christmas.
No one’s mentioned a Kegerator yet?
chique Do you have one on the farm? I’m still trying to talk Mrs. NurseCarmen into the long drive, I could tell her I’m doing research for my basement!
LifeOnWry Your husband is clearly some sort of Man-God. I wish I had posted before I completed the plumbing. :smack: urinal! A gas mask will certainly be adorning my bathroom wall. Or maybe even on the butler. Where the hell did he find a condom machine!?!?
Lynn BodiniHow could I space Archee? I assure you I’ll be perusing that site again. Thanks for kick-starting my brain on that one.
Joe KBowling pins, I agree. Cheap (free!) and can hold up to target practice with large caliber weaponry. I must get me a box-a-pins.
MikeGI am not worthy. Nor wealthy 
Wartime ConsiglioriI suck at darts. My wife sucks at darts. my 2YO sucks at darts. plastic tips for safety. I must agree, plastic/electric is a bit of a cop out.
Condom machine, if you can believe it, was a gift from his two elderly aunts, who cadged it off a guy who was closing his bar. But, you can buy 'em on eBay too.
Maybe I’ll get him a butler, too. I saw one in the Paragon catalogue.
ala “Cribs”: You must get a stripper pole.
I have six traffic cones in my bedroom.
A gun rack of some kind is a necessity. You don’t have to put firearms in it… golf clubs, paintball guns, swords… whatever. Just a gun rack. Don’t forget a hideously huge souvenier ceramic beer stein. Toolbox, can of WD-40 and some duct tape.
Beatles bass drum head on my wall, flanked by posters of the fab four.
Where’d you get the velvet Elvis? I live in Georgia, and up until a few years ago, you could find 'em being sold alongside the highway, but I haven’t seen 'em in quite some time.
Q
This is sad, but. . . I’m a girl, and I’m jealous of this room.
I had another idea - how about a slot-car racing track?
A SLOT MACHINE!!

You’ll need one of those sand-weighted blowup punching figures for when your team loses, the kind that always right themselves to 82 degrees.
