xkcd #149, "Sandwich" (2006)

Sudo make me a sandwich.

— xkcd • 2005

Behind the line

What it means

Our interpretation.

The joke works because sudo is the word that ends every permissions argument: if the machine won't let you, you add it and it does. Here it overrides a person instead of a computer, and the friend simply obeys. It became the stock reply for anyone asking a favour in nerd company, and the sudo project itself later adopted a sandwich as its logo.

In xkcd strip 149, "Sandwich", posted on 28 August 2006, Cueball sits on a couch and tells a friend to make him a sandwich. The friend refuses and tells him to make it himself. Cueball tries again with one extra word at the front, the Unix command that runs anything as the all-powerful root user, and the friend gives in with a flat "Okay." The title text adds a gag about policy, saying a proper user policy apparently means Simon Says.
