Blackadder

[Baldrick explains his cunning plan to save the Prince]

Baldrick:
Well, I just thought; this Wellington bloke's been in Europe for years. You don't know what he looks like, he don't know what you look like, so why don't you get someone else to fight the duel instead of you?

The Prince Regent:
But I'm the Prince Regent! My portrait hangs on every wall!

Blackadder:
Answer that, Baldrick.

Baldrick:
Well, my cousin Bert Baldrick, Mr. Gainsborough's butler's dogsbody, says that he's heard all portraits look the same these days, 'cause they're painted to a romantic ideal, rather than as a true depiction of the idiosyncratic facial qualities of the person in question.

[Blackadder and the Prince look astonished]

Blackadder:
Your cousin Bert obviously has a larger vocabulary than you do.
