Happy Happy Halloween
From Screamer Wiki
Happy Happy Halloween!
This pretends to be a TV show with dancing faces. (This is actually the Silver Shamrock mask commercial from Halloween 3) At the part where a picture of a pumpkin keeps flashing on the TV, a scary zombie jumps up from the upper left with a scream.
