Robot Chicken, Season 6

Flik:
[making a speech to the Circus Bugs] Everyone rest up! In the morning, we start the long trip home to confront Hopper and his evil gang! [hears loud music and cheering, and finds Mr. Mayfly having a party] 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...[BLEEP] 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!

[We 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! [laughs about this. The next shot is of her giving birth, making Flik cover his ears in frustration] Get it out of me!

[A handful of eggs come out of her as she screams; then we slide to the middle-aged 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; the next shot is the elderly Mrs. Mayfly crying. Flik, still waiting for everything to be over, is in fetal position]

Mr. Mayfly:
[depressed] Aw, what was the point of it all? LIVE, REPRODUCE, DIE?! IT'S A SICK JOKE! A SICK- [gags and dies, making his wife follow suit]

Flik:
[looks at the dead couple; relieved] Oh, finally.

Baby Mayfly:
[hatched from one of the eggs] Wo-hoooo! Party time, baby!

Flik:
[irritated] OHHH, [BLEEP] ME!
