Right, listen all you chickens.
What you do when the opposition start giving it large on your manor-
You see them approaching so take out a rusty, old scraper from your pouch. Even if you're 100% wfp, wear a pouch- cheap, blue plastic or otherwise- with a dirty, rusty old scraper inside.
Then to start to shave your face with the scraper and say "be with you in a minute, sunshine".
Then "that's better; now how can I help you?"
You won't get any agg, I promise you.
