This is probably a decidedly racist joke, but i repeat it here because i think its one of the sharpest verbal ripostes i've heard in a long time.
Its a well known fact that Britain's lax immigration laws in the late 1970s/early 1980s resulted in an influx of many immigrants, a large number of whom were from India -- Bengalis, Sikhs, Hindus, Muslims, etc.
Present time, Immigration at Heathrow Airport, UK:
Visitor: Hello there, here's my passport.
Officer: Gooooood day, sir (said in the curious accent Indians have when they speak English)
Officer: Sooo... hooowww long were you planniiiing to staaay in Britain, sir?
Visitor: Obviously, not as long as you are.
Nasty, eh?
