The Sink & Daddy: the Commonality

So E and I finished washing the dishes.

When we drained the sink, it made a really loud gurgling sound.

E: "What was that!?" --obviously thinking it sounded cool.

Me: "that was the sound of the sink draining."

E: "Cool, it sounded like burping and farting all in one."

Me: "So it sounded like daddy?"

E: "YEAH!"
