Raj, Sheldon and others in “The Friendship Algorithm”

Gentlemen, I put it to you: the worst tapioca pudding is better than the best pudding of any other flavor.

First off, that's axiomatically wrong, because the best pudding is chocolate. Secondly, the organic structure of tapioca makes it a jiggling bowl of potential death. It is extracted from the plant -

[deliberately interrupting him] Hey, I'm thinking of growing a moustache.

[playing along] Aaah… No kidding. Fu Manchu? A Handlebar? Pencil?

[desperately] It's extracted from the plant -

I'm not sure yet. You know. George Clooney has one.

Really? I once saw him at Ralph's. He was buying tequila.

Oh. You'd think a guy like that would have some kind of booze lackey.

[smiling] Alright. This is cruel. We'd better let him finish before his head explodes.

Alright, Sheldon, why is tapioca - ?

[very quickly, in a rambling manner] Tapioca is extracted from the root of the plant Manihot Esculenta. Due to a high concentration of cyanide, it is poisonous in its raw form and lethal if prepared improperly! [takes a drink of water]

Feel better now?

[continuing] It is also indigenous to Brazil, as is the cocoa bean from which we get chocolate, the best pudding, and you [Leonard] promised you wouldn't do that anymore!
