A family. Extremely loud, obnoxious and often times, just outright weird. DO NOT GIVE THEM NOISE MAKERS. Way too many people in one house, and excessive swearing often happens. If you are within a one mile radius of them and a gun, take caution. Donlons are psycho, but you cannot help loving them.
Person 1: What is all that noise?!?!?!?!?
Person 2: Oh, thats just the Donlons.
