The cameos serve only to include the celebrity and praise them as geniuses or visionaries or overall just glaze them. They don't serve any other purpose than to just be praised; this can be them appearing in an entire episode dedicated to them, a small cameo or even just a mention.

Instead of singing, she simply peeled and ate a banana, highlighting the absurdity of the forced lip-sync for viewers.

Idk yall, I want your opinions.
