Foster's Home for Imaginary Friends, Season 3

Mac:
Is this the flight to Europe?

Ticket Agent:
Yes, it is. You just made it.

Mac:
We made it! We made it!

Ticket Agent:
Tickets?

Mac:
I've got 'em! [tries to get them out of his backpack but realizes they're not in there]

[Later, everyone returns home and blame Mac for not having the tickets]

Frankie:
[annoyed] Grandma, we're home!

Mr. Herriman:
Oh, Master Mac. I'm most upset by your careless behavior. My schedule is null and void. [annoyingly rips his schedule into pieces]

Coco:
Co! Coco coco co! ("Way to lose the tickets, Mac!")

Edurado:
[imitating Paco] I es muy disappointed in you, Señor Mac. [glares at Mac with an annoyed scowl and storms off]

Wilt:
[upset] Usually, I can forgive anything, but… [sniffles sadly as he's about to cry] I'm sorry. This is going to take me a while. Is that okay? [walks away]

Bloo:
Real nice, Mac. Do you know how long I've been looking forward to this trip? I wouldn't give it up for the world! [whispers] For the world! [storms off]

Mac:
[dumbfounded] But they were in my backpack! I swear!
