"... dogs come from the moon, not the Sun!"
Alice says something ridiculous. Bob responds with this Stock Phrase (or some close relative), then explains why Alice's statement is ridiculous. Of course, Bob's justification is either as absurd, more absurd, or otherwise not a rebuttal one would normally make to the original statement.
A common variant is that Alice's original statement was an attempt to guess what Bob is planning or doing. ("So you're going to just storm the castle?" "Don't be absurd. I'm going to storm the castle carrying this marionette. Sheesh.")
Not quite the same as the usage of the phrase by Funny Foreigner Balki Bartokomous in the sitcom Perfect Strangers. (He would say it when suspected of doing something wrong, but usually wouldn't follow up with a nonsensical rebuttal.)
See Insane Troll Logic. Somewhat related to Voodoo Shark (when Real Life fiction-creators are seen doing this themselves — albeit not in response to a theory they find absurd). May also involve Distinction Without a Difference ("No, I'm not eating an eraser. I'm eating two erasers"). Compare Worrying for the Wrong Reason ("Sharks? Don't be silly. The crocodiles will get you first").

MacAvoy, during Martha's first conversation with Mayland Long, he tells her a version of the tale of Thomas the Rhymer, which continues past the usual ending point to talk about Thomas' son. When he finishes, she remarks that he tells it with such authority she could almost believe he'd had it from Thomas in person.

Launchpad: Don't be silly, DW; this log gave me the directions. The cow just warned us not to order the coffee.
