Eddie (Ken Osmond) offers to do the breakfast dishes and tells Wally and Beaver he wasn't kidding. As Eddie starts to fill up the sink, Ken Osmond is seen to be merely mimicking turning on the faucets.
While Ward and June are washing dishes, Ward comments that Wally and Eddie have been friends for "4 or 5 years now". But in Nobody Loves Me (1962), it's revealed that the boys have been friends since they were toddlers.
