When you're parked infront of the gogglebox with your TV tray, don't you think your TV is missing some of the fun? Screw a $40 ScreenDeck into the TV's VESA holes to hold up his peripherals too. [Amazon via Unplggd]
I currently have my center channel stuck to the top of my TV using some of that sticky stretchy playdough-like stuff you find in office supply stores. It's not too elegent, but it holds it up pretty well and you can't really see it. The edge of the speaker hangs just past the edge of the TV and my Wii sensor bar is velcro'd to the bottom of it. It doesn't look great, but not bad for some cheap DIY work.
