My audio clip:
It's a piece of dialogue from the film 'Welcome to the Jungle'.
The piece is of Christopher Walker's character 'Hatcher' talking to some workers about the protagonists of the film (Dwane Johnson and Sean William Scott).
He uses the metaphor of a kid's tooth being stolen before the tooth fairy gets it to explain his feelings.
The clip is about a minute long, and starts at 31:30 on the films timeline.
