Flik: Everyone rest up! In the morning, we start the long trip home to confront Hopper and his evil gang!
Flik hears loud music and cheering, and finds Mr. Mayfly having a party.
Flik: Excuse me, Mr. Mayfly, can you keep it down? We have- we have a really big day tomorrow.
Mr. Mayfly: Oh, really? Well, my entire lifespan is three hours, so... FUCK YOUR BIG DAY!
Mrs. Mayfly: Oh, a man at last! I've already been alive a half-hour, and I need to get pregnant right now!
Mr. Mayfly: Oh yeah!
Cut to Flik trying to sleep while the two mayflies make love. Flik is annoyed by their sex.
Mrs. Mayfly: Oh, my God, this is the best sex of my whole life!
She laughs about this and the next shot is of her giving birth, making Flik cover his ears in frustration.
Mrs. Mayfly: (groans) Get it out of me!
A handful of eggs come out of her as she screams. Slide transition to the couple arguing while Flik punches himself in the head.
Mr. Mayfly: Look, I've got at least 47 good minutes left in me and I'll be damned if I'm gonna waste them!
Mrs. Mayfly: You're a midlife cliche!
Flik groans and punches himself some more. Transition to Mrs. Mayfly crying beside her depressed husband. Flik, still waiting for everything to be over, is in fetal position.
Mr. Mayfly: Aw, what was the point of it all? LIVE, REPRODUCE, DIE?! IT'S A SICK JOKE! A SICK-
He gags and dies, making his wife follow suit. Now relieved, Flik looks at the dead couple.
Flik: Oh, finally.
But to his irritation, a baby mayfly hatches from one of the eggs.
Hatchling: Wo-hoooo! Party time, baby!
Flik: OHHH, FUCK ME!
Static transition to the next skit.
