"You can call us Aaron Burr from the way we're dropping Hamiltons." (This refers to the 1804 duel in which then-Vice President Burr killed Alexander Hamilton, whose portrait appears on the ten dollar bill.)
A subtle derogatory term for Pakistanis. Derived from the Scottish football team Hamilton Academicals, usually known as "The Accies". It rhymes with Pakis, hence Hamiltons.
"Agnes have you seen who has moved in next door?"
"Oh yes! Bloody Hamiltons"
"O well, there goes the neighbourhood!!"
(nods to Monty Python there folks)
