Get the RFNmug. They're supposed to stand for "Real Fucking Nightmare" but the only thing you should be scared of is the chomos in their family! IE: Mike. Beware of this family, keep your back to the wall at all times, children. They're completely harmless, unless you count the barking they do in Pal. Hide yo kids not yo wife, cause they're out there like Pedo Bear..
