1x12 - Maniac Mansion

For Fred and Casey's 16th anniversary, Fred goes to the mall and gets her two tickets to see her old band-mate Jaz Pope. The family watches a video of Casey and Jaz to see what she was like. After Jaz' performance, which really stunk, Casey is debating whether or not to tell Jaz the truth about how bad her music is. Casey decides not to, and Fred, who Jaz thinks is Casey's old boyfriend Snake, doesn't help either. Jaz comes over to the mansion and she and Casey give a concert to the family.
