you're too late, you'll never find 'em now
A prominent phrase said by Swiper the Fox in almost every episode of the hit cartoon "Dora the Explorer". He steals the goods from Dora and Boots and says this.
Heh, heh, heh. You're toooo late, you'll never find your backpack now. {He then throws the backpack into bushes, then runs the opposite direction. I wonder what his motive is, I mean come on. And same thing with the grumpy old troll, who lives under the bridge.
