South Park, Season 24

Randy:
[limps next to Jimbo, whispering to him in soft anger] Just fucking shut up! You have no idea if it's because of the Special! You could just be sick again 'cause you're a fat, fucking alcoholic! And I am NOT going to jail for you! [smacks Jimbo in the face and limps away holding his crotch]

[Hells Pass Hospital; the doctor looks closer at the mustache on Gerald's face]

Doctor:
And you say you've never had a mustache before?

Gerald:
No! Never! I just came outta nowhere!

Sheila:
How could this happen, Doctor?

Doctor:
Have you put anything toxic in your body lately? Any drugs or alcohol?

Gerald:
No! I mean… I've enjoyed a little of the Pandemic Special.

Doctor:
Oh, no, no, no. That…that's totally fine.

Nurse:
Doctor, you better come to the emergency room!

Doctor:
[shocked] Holy shit!

[The emergency room is packed with all male and female patients with pandemic mustaches on their faces]
