How do I swallow a duck?

This question, mostly associated with BansheePlant, is often repeated in live streams as a running gag.

Origin of the joke
Matt and Banshee, to put it lightly, have a strange sense of humor - their Direct Messages are arguably some of the funniest instances of random running gags and In-Jokes. With this knowledge, it should be no surprise that their humor extends to using ducks as a source of hilarity; in fact, you probably should have expected it. The idea of using a duck as a means of making quick humor was mainly Banshee's idea, though it was Matt that coined the misspelling "KWAAQ" (an extended version of the phonetics of the word "Quack") as a response to the question.
 * Banshee: What is the correct way of swallowing a duck?
 * Matt: Put it in break first, alive.

KWAAQ would later find itself as a running gag on the channel - whereby a sound of a duck quacking would play after an instant in which Matt either calls hypocrisy or doesn't think a thing is particularly good, as well as adding silliness to a serious situation. It would also later be a 1 second shitpost posted on the channel with no context given to the viewers, probably leaving them quite confused.
