Me and a pal, when we were kids, were walking down his street one day when the public phone on the street rang, so I picked it up. Bird on the other end asked if it was the pizze delivery place (which was right next to the phone box, so must have had a similar number which she misdialed)

So I said yes Took her order, told her it'd be about half an hour, any longer than 45mins and it'd be free
