Ferb: Don't remind me. Phineas: Sorry bro, it's just that we've done almost everything. Ferb: Well, why don't we try going to a different dimension. Phineas: Say that doesn't sound half bad.

Isabella: Cool, I've always wanted to go to another universe and the Fireside Girls need to get their Portal Maintenance Patch. Phineas: Cool, we'll get started right away!
