Forget those wimpy remote-controlled pests that seem to be proliferating by the minute. You really want something annoying? Get an RC Hummer H2 replica that's a full 2.5 feet long. That's easily big enough to knock over your idiot uncle before Christmas dinner has even begun. Making this beast even more irritating are flashing lights and spinning rims, so it might be tough to sneak up on guests. But at cruising speeds up to 20 mph, you won't need too much stealth to catch them.
