The Quibbler 

Part of a phrase that usually goes (after one has stated a very unbelievable story) Oh yeah? Where'd you hear that? the Quibbler? -laughs ensue- This references the newspaper The Quibbler that Xenophilius Lovegood of the Harry Potter series prints on a regular basis, which is usually full of ridiculous sightings of fictional creatures and outlandish stories.

Rutherford: Did you know that dogs go to heaven? God told me last night!

Cornelius: HA! Where'd you hear that? The Quibbler?

-laughter from all but Rutherford-

Rutherford: -cries-
