Hen: How do you spell "caw"?
Me: Like the <insert bird caw sound here> kind of caw?
Hen: No. Like "caw"?
Me: Use it in a sentence.
Hen, pausing for a millisecond before breathing deeply and saying in a British accent: RONALD WEASLEY, HOW DARE YOU STEAL THAT CAH.
Followed by uproarious laughter from the both of us.
