Russell tells Timmy about how once long ago tried to be in an Acapella group but froze and how he always wondered what it would have been like if he succeeded after seeing Timmy's group sing. As usual Russell always has a double edged sword mentality especially at Timmy's expense. Jeff is fantastic in this episode ... Liz moved in and Audrey and Jeff just can't take her disgusting ways anymore and try to get her to leave.... *Fun fact* ..when David Spade does his "Acapella" rehearsal with Timmy's group, "The Toners" ... It's actually Adam "Oliver Hudson" singing behind the curtains as Russells just lip syncing along... Listen closely you can tell it's Adams voice ... Adam can sing really well in real life.
