Fineasz i Ferb Sezon 1 Odcinek 13: Are You My Mummy?

Crack That Whip: While skating at the roller rink, Phineas, Ferb and Candace realize their grandma is an awesome skater... who used to be part of a championship roller derby team. They decide it would be fun to bring back the old days and set up a roller derby rink in the backyard so Grandma Betty Jo can skate against her old rival Gretchen, who happens to be Jeremy's grandma. The old ladies get their grandkids to team up with them and now Candace is worried that Jeremy won't like her if she beats him. The Best Lazy Day Ever: It's such a nice day that Phineas and Ferb have decided to do nothing. That's right, nothing at all. But Candace doesn't believe them and insists that they are up to something. She drives herself into a complete panic and ends up building something she thinks Phineas and Ferb would build just so she can get on with her day and make it to her parade with Jeremy in time.
