David Romero Cartoons
 

All relatively short (longest is less than five and a half minutes) with gritty textures for the backgrounds. Only one line of dialogue between the three of them. None of them have the most creative stories ever told but they're stripped down and efficient. Personally I find there tends to be something kind of cute about how simply the people in them are drawn, which makes the whole deal a little scarier.
