>Or why a house in Owls Green, a village of about 20 houses near Ipswich, would be numbered 2820 (cute).

For those who aren't native British/English-speaking, this is presumably a cute reference to the village's name of *Owls* Green, since at least in the UK the onomatopoeia for one of an owl's sounds is "too-wit too-woo", to which "two-eight two-oh" is similar sounding.
