Papa: It doesn't matter where you came from. What matters is who you choose to be.
Grouchy Smurf: Every time a smurf toots, someone smiles.
Papa: Listen up, smurfs. I saved water form the last blue moon for just such an occasion. I was able to smurf it into these smurf-portation crystals.
Brainy Smurf: Oh, so you don't need a portal. Very clever, Papa.
Papa: Smurf-xactly.
Grouchy Smurf: This was supposed to be Hefty.
Clumsy Smurf: Sorry, my bad.
Vanity Smurf: I get so puffy when I travel.
