The Weekend Aunt Helen Came

The boy's mother, Jennifer, leaves for the weekend leaving the father, Roger, in charge. He lets the kids run wild. Alfie and Dee Dee's Aunt Helen then comes to oversee the house until Jennifer gets back. Alfie throws a basketball at Goo, which hits him in the head, giving him temporary amnesia. In this case of memory loss, Goo acts like a nerd, doing homework on a weekend, wanting to be called Milton instead of Goo, calling Alfie Alfred, etc. The only thing that will reverse this is another hit in the head.
