Serena is at Samantha's house when Larry Tate pays a visit. Larry is usually worried about getting as rich as possible as quickly as possible but on this occasion, he is more interested in worrying about the fact that he feels he is growing old. Serena was probably the wrong person to impart that information to as she immediately uses magic to make Larry ten years younger. To say that everyone is surprised by the transformation is an understatement, but Larry keeps getting younger and younger, almost by the minute, and that becomes positively alarming!
Samantha quickly becomes aware of what Serena has done and insists that she put things back the way they were. Reluctantly, she does so, but we are left wondering whether or not Larry is actually happy with being his 'old self' again.
