My husband’s birthday is almost upon me and as usual I have no idea what to get him. I don’t really know what I can tell you about him that will help, either. He um…likes working, sleeping, and watching TV. 
If anyone can give me good ideas on what to buy or do for a man’s birthday*, I would really appreciate it (and I’m sure a lot of other clueless females will file it away for future reference also!)
*less than $100 bucks please!
New games for PS or XBox if you know what he likes. Play with him all day.
Tickets to a pro game.
Tickets to a concert.
Sexy night at a hotel (buy a Fredericks of Hollywood outfit) (My ex LOVED this gift)
Get him a bunch of CD’s by his favorite artist.
A threesome - he’d love a threesome.
solidly thumps don’t ask
Ain’t happening. Right as you may be.
Get him a couple of seasons or a series box set of whatever TV show he likes to watch.
Get him a tool- doesn’t matter what, guys love tools. Or a gift cert to Home Depot or Lowe’s if you’re really stumped.
Get him a couple cases of whatever beer he likes to drink, or bottles of wine/booze.
Get yourself some lingerie/toys/rubber wear, and carve out a time and place to show him what you got. And I mean show him. [the best birthday present I ever got was from a then-girlfriend who gave me a card on the morning of my birthday that said “It’s your birthday- use me for your pleasure”. And I did.]
Get him this, if cameras are his thing: http://gorillapod.com/products.html
Get him a massage (no, not a “happy ending” massage, a real massage by a professional masseuse). I always feel like a new man after one.
What’s his job? What does he watch on TV?
With no more detail, all I can suggest is a DVD box set of a TV show. Or maybe an alarm clock. 
Or maybe a nice watch. I got this for myself recently and like it a lot. (But this particular one has a couple of caveats: it’s a mechanical “automatic” watch so it’s not as accurate as a quartz watch, and it stops if you don’t wear it for a couple of days. And the design is very close to a Rolex so some people will scoff at it as a knockoff or “fake”. On the other hand, it’s very solid and you can look at the mechanism through the transparent back.)
I hate to stereotype, but does he like comic strips? Some of the popular ones, like Far Side, Calvin and Hobbes and Peanuts, are available as hardcover “complete collections”. The Far Side collection is just under $100.
Anything from http://www.thinkgeek.com.
Or this ought to get him up off the couch! 
I am taking all ideas (except one) under consideration, but none of them seem to be The One* just yet. Keep 'em coming, I can always use them at Christmas or next year or whenever I feel obligated to prove my affection.
By the way, his job is managing a group of med lab techs (snore) and he watches a lot of the Comedy Channel.
*I’m gonna *find * somebody to give that marshmallow thing to.
My BIL was thrilled with the massage I got him. It was $30 through the Park District, but I’m sure you could get an affordable one at a chic day spa.
Tickets to something
Music
Movies
Lessons?
This might sound silly, but how about taking him to a really good, off the hook restaurant?
That’s what my hubby loves - instead of a “thing”, I take him somewhere - like to an outrageously good steak place or something. Know what I mean?
Or concert tickets.
Or sports tickets.
A blue shirt, maybe two. Guys who don’t want anything always need shirts and it’s statistically proven* that 99.8% of all guys favor blue.
*not actually statistically proven.
At the moment, I’m kind of leaning toward the massage idea. I don’t know if he’d really be comfortable going to do such a thing, but he does have some of them thar metrosexual tendencies.

That’s all I got.
Have you considered plush microbes? You can probably buy the whole set for $100…
Most men like toys. Would he be interested in a train set, RC car, slot car set, LEGO set, etc?
You can adopt a dog for less than $100, but it’d end up costing a lot more in the long run…
If you resort to “gift product” type stuff, I think Josh Simpson’s planets are pretty. I saw it mentioned in another tread recently and I’m very tempted.
