Edmund: (removing the pencils, looks at Baldrick) Fat chance! Now, all we have to do is wait. Baldrick, fix us some coffee, will you? And try to make it taste slightly less like mud this time. 

Baldrick: Not easy, I'm afraid, Captain. 

Edmund: Why is this? 

Baldrick: 'cause it is mud. We ran out of coffee thirteen months ago. 

Edmund: So every time I've drunk your coffee since, I have in fact been drinking hot mud... 

Baldrick: With sugar. 

Edmund: Which of course makes all the difference. 

Baldrick: Well, it would do if we had any sugar, but, unfortunately, we ran out New Year's Eve 1915, since when I've been using sugar substitute. 

Edmund: Which is...? 

Baldrick: Dandruff. 

Edmund: Brilliant. 

Baldrick: Still, I could add some milk this time -- well, saliva... 

Edmund: No, no, thank you, Baldrick. Call me Mr Picky, but I think I'll cancel the coffee.
