On the desk, a personalized, autographed picture of Dick Cheney in hunting gear.
And to go with the sniper manual, some actual long range targets with all shots in the black.
Two shrines, one built around a bejewled chastity belt and the other around medieval looking genital cuffs.
In the corner there needs to be a car battery, a pair of jumper cables and a book entitled “Testicles for Dummies”.
When I was in high school I had a date for Homecomming. She wasn’t allowed to come with me in my car so her parents were going to drop her off. Well she called me and told me it was ok because her father wasn’t going to be home and he was the one who objected in the first place.
When I went to pick her up her father came home as we were leaving. He had just come back from hunting and was carrying his firearm. Not the kind of thing a young guy wants to see just before a date.
May I edit-check this document? I found a few errors, nothing serious.
No questions about music choices? 
That application needs additional questions about the direction in which the bill of a baseball cap is meant to point (when not wearing a catcher’s mask) and the proper body part around which the top of one’s pants should be.
Mouse_Maven, if your spouse has an inner super-villain, he needs a large video screen (or a bank of 9-16 smaller ones, arranged in a rectangle) occupying a 7’ x 5’ section of the wall behind his desk. And the desktop should have a map of either the world, or some specific section thereof designated for conquest.
Yeah, but you have to record the score from *Apocalypse Now * so that there’s the sound of helicopters and machine guns and screaming.
Mouse_Maven, the method I found most effective was to go to the shooting range on the day of the date, pay extra for the targets that are pictures of people, then shoot out the faces and crotches. When the young man arrived to pick up my daughter, he found me cleaning my gun with the targets spread out on the floor beside me.
You’ll need to take several pictures of tombstones from a local cemetary, preferably still surrounded by fresh dirt, and hang them on the wall. On each, tape an empty large bore rifle cartridge and underneath, in barely legible scrawl, write the words “I told you.”
I like this. On my desk at work maybe, since I have only sons.
Make sure that the chairs opposite the desk have legs that are cut off by about 6 inches to make them look up at your husband. Also, a jar on the desk discretely labeled “Dust of Mousling’s Former Boyfriends”.
(I have 3 daughters)
A yard glass. Mounted on the wall. Prospective suitors must down a yard of ale or cider (if you’re feeling cruel, use vodka) or take its place. 
Thank you for not calling it a “man room”, “man cave”, or any variation thereof.
My stepson has volunteered to vet any boys that tries to date my daughter.
Since he lives in Australia he sets the financial bar fairly high at the start.
I expect other evaluations will involve Aussie flora and fauna. I advise one-way tickets

I second not getting too heavy on the HP Lovecraft. Any guy who recognizes the name is highly likely to go “oh, WOW!” and want to borrow the books. Of course, if you decide that you’re not just interested in scaring possible suitors away but actually on finding acceptable ones, books by your favorite authors (in sober editions, avoid ones with butterflies on the cover) are a must.
Any suitor who sees Alice Through the Mirror and makes an intelligent remark should be given some leeway, for example. Have you noticed how much rarer than Alice in Wonderland it is?
One side of the room (which may include the huge display, assuming that you don’t go for the multidisplay choice) should be a floor-to-ceiling bookcase. The books should be real; several shelves dedicated to scientific magazines would terrify a suitable percentile of suitors. There should be a large IT section and several tasteful pieces of bric-a-brac; for example, a pair of those painted ceramic containers which were used by old pharmacies to store ingredients (names must be in Latin) and several transparent ones containing samples of your own work.
At least one tapeworm must be among the formol-preserved delicacies. This seems to trigger the yucks in a large number of people, judging by reactions observed in science museums (even though most of said people didn’t even know what a tapeworm is, from what I overheard).
If you’re going for the whole “stuffed animals and multiple TVs”, you can use the wall containing the door to hold the bookcase (in which case, said bookcase must extend above the door). This causes a sort of tunnel at the entrance. The opposite wall should be occupied by the screens, backlighting the Grizzly; there should be no chairs other than his own or perhaps another one which the suitor is not allowed to use. Since your husband is a large man, having the desk and chair on a plinth is optional.
Oh sure, that’s good now, but when the Mousling gets married there’ll be a huge line of people waiting to make a request of Mouse_Spouse.
This problem can also be fixed with a “No Canadians Need Apply” line. 
That wouldn’t scare me off; I’d be fascinated by such a bookshelf.
On the other hand, any vibe that says, “Not My Religion or Ethnic Group = Evil” or “Gay = Evil” would send me screaming for the exits.
Why would the girl be dating Canadians? :mad:
How about a jar labeled “Testicles FROM Dummies”?
And let’s not forget the Ten Rules for Dating My Daughter framed and hung on the wall. With a copy for them to initial each rule on the desk.
