If you want a surefire way of sleeping out on the living room floor at night without a blanket, that's pretty easy. All you need to do is freak your girlfriend out with the remote controlled flying cockroach. It looks pretty much like the real deal, and people who have a phobia towards these disgusting insects probably won't have the intestinal fortitude to check out whether it is real or not in the first place anyway, so no worries about getting found out. There is the danger of somebody whacking it with a shoe or fly swatter in mid-flight though, rendering your $59 toy useless if the force is hard enough. The main drawback would be its lack of battery life - 30 minutes' worth of charging results in a mere 5 minutes of flying time.
