Mr. Wyland, Mr. Garrison's substitute, informs the class of Kyle Broflovski being ill and makes them create a "Get Well Soon" card for Kyle. The class uses the supplies they were given and makes Butters into a walking "Get Well Soon" card. Later at Kyle's house, Stan Marsh makes Butters perform this song.
We're so sorry you're not feeling well.
We hope you're better soon.
So we're bringing you some sunshine
By, um, singing you this tune:
Everybody misses you
And though we hate to cause a fuss
We'd like to say, "Get well soon!"
And "Please don't die on us."
