Blackadder: Right Baldrick, let's try again shall we? This is called adding. If I have two beans, and then I add two more beans, what do I have?

Baldrick: Some beans.

Blackadder: Yes... and no. Let's try again shall we? I have two beans, then I add two more beans. What does that make?

Baldrick: A very small casserole.

Blackadder: Baldrick, the ape creatures of the Indus have mastered this. Now try again. One, two, three, four. So how many are there?

Baldrick: Three.

Blackadder: What?

Baldrick: ...and that one.

Blackadder: Three and that one. So if I add that one to the three what will I have?

Baldrick: Oh. Some beans.
