(Also, I banged ya mum ;))
When someone calls you, say this: "Hi, welcome to Dave’s Orphanage. You make them, we take them. How may I help you?"
What Kind of Hardware store can't orphans go into?
Home Depot.
April Fool's joke: Go to an orphanage and tell them, "Their parents came back."
Do you want to know why they call it an orphanage? Because they couldn't call it orphans home.
