To be honest, Christmas is the time of year when you DON’T want to be spying on the neighbours. They’ll only be having blistering arguments about who forgot to defrost the turkey / why the kids don’t deserve a Wii / who invited smelly old Aunt Elsie anyway. It’s not exactly fascinating stuff.
Nevertheless, if you really must spend the festive season snooping on next-door, you’ll be wanting the new Spion Orbiter Electronic Listening Device. It lets you earwig on conversations up to 300 feet away, and even record snippets for later blackmail. Plus it looks like an alien killing machine, which always helps.
