Phineas and Ferb, Season 1

Candace:
Just wait 'til Mom hears about-- Then again, you guys always seem to make everything disappear before Mom gets home. But if I take the evidence to her at the Bowl-R-Ama, then she'll have to believe me!

[In Candace's fantasy]

Mom:
Oh, Candace! You were right about Phineas and Ferb this whole time. We should've believed you.

Dad:
And just to express how sorry we are, here's my credit card. You have our permission to ruin us financially.

Jeremy:
Candace, that is so cool how you busted your brothers like that! Will you marry me?

[Back in reality]

Phineas:
So you wanna give it a try?

Candace:
I do, Jeremy! I mean, uh... I'd love to give it a try.
