I'm probably going to attract trolls with heavy cognitive dissonance by this post, who didn't think through its meaning, but whatever:

Nostriches: Potato, become an egg!

Potato: How? I'm a potato.

Nostriches: You need the boiling water!

Potato: I told you, I'm a potato, it doesn't harden me, it softens me!

Nostriches: Well, become an egg then!

(return to second line and repeat, or go off into how being a potato is a moral failing etc.)

(The mandatory: Not all nostriches of course. But probably 3/4 of them.)
