I have had the urgent need and have used a toilet plunger many times, but never a gun. Not sure I would decorate my man cave with plungers. Well, maybe one or two.
If I was in that gun room, I would never leave. Even if the owner does seem to have an odd fetish for Browning Automatics and M1 derivatives. The first one seems tacky and twee in comparison.
If I had a man-cave it would definitely have a jukebox. Something like this 1958 Disc-O-Matic "Gama" from the atomic age, filled with 1960s classic rock.
Check out that nuclear green glow. It's like the thing is powered by uranium!
The OP had me at Lagavulin 16.
Foggy, that is a FINE white spot collection.
My own den is not quite so grand as the OP's -- which I'd call opulent -- but it's a comfy retreat.
