I was watching the tv series, "The rest of us." And this week, Ellie makes this pun:
I stayed up all night wondering where the sun went...and then it dawned on me
She read it from the book by Will Livingston titled, "No Pun Intended: Volume Too". So I assume the joke includes some pun but I don't know where.
Or the joke is fun because the guy is stupid enough to stay up all night to figure out the simple fact?
I don't get why this joke is so funny.
