Rudy buried him in the back yard after he made a satanic pate' out of his liver.
I hadn't even thought about Dave not being there - and to top it off Carol and Ray go off on, I guess, another vacation to get away from the neighborhood and DAve has to stay with his horrible cousins. Sucks to be Dave.
I like how Dave interacts with Ricky the best. (They can be seen in the background during the scene where Art and Ray see Hans Klopek emerge from the house.)
Ricky: Go for it, Mr. Peterson — yes! Ha-ha! Whoo! Good goin’, man!
