Empty spaces attract junk like tv screens attract dust. Junk paralyzes progress. Take a look at the junk and if it really IS just stuff taking up space---get rid of it. If it's yours and you're not using it---get rid of it. If it's his, move it out.
Once the junk is gone taking positive action will be easier. A man, a chair and a flat-screen don't take up much space so work around 'em. Give him a headset so he can hear the sports and you don't have to.
The passive/aggressive advice is entertaining and funny but not conducive to good relationships. Proverbs 31: 10-12
