If you feel you need to make your office more manly, all you need is a universal remote. Yes people, a remote. Program every electronic device into your remote and don't be shy fellas. You are so not above programming your swivel chair to turn around without the slightest effort from you when a guest enters.
Oh and you know how your wife has been nagging you to take those nasty couches you had in college to the dump? Well bring them to work and have your friends over on their lunch breaks to watch the game you TiVo'ed last night. Finish with a mini fridge filled with nice cold brewskies and you've got your MAN OFFICE.
