A helpful mnemonic device from Comedy Bang Bang ep. 150.
K = Kid; he’s a kid
N = Naughty; he’s a naughty kid
I = I am the person who will grab the knife
F = Friend; he’s not our friend
E = Education (or, Every Good Boy Deserves Fudge)
G = Gadzooks! I’m terrified of this little child who is going to stab me with the knife!
R = Really? Don’t you think it’s time you grabbed the knife?
A = A shame it would be, should the boy grab the knife first, then stab us!
B = Boy
As a person who is often followed by stabby street urchins, I find this incredibly useful.
