 * In the premiere episode "Crack That Whip," when Phineas, Ferb and Candace learn their Grandma Betty Jo is an awesome skater who was once part of a championship roller derby team, they set up a roller derby rink in the backyard so she can skate against her former rival, Gretchen (voiced by Vicki Lawrence), who happens to be Jeremy's grandma. Meanwhile Doofenshmirtz wants to destroy a statue of a bearded man because it's mocking his inability to grow facial hair. [Note: Vicki Lawrence's role was for Hildegard, not Gretchen.]
