The line is drawn @ Italians. I'm a public sector employee and senior managers will speak to me in "Luigi-the-organ-grinder" affected accent. Or in a meeting, they suggested not to piss me off or I'd whack them. These are senior level folks who would never ask my black colleague for some fried chicken or walk up to my Chinese admin ass't and say sho sholley, prease. It's the last bastion of acceptable racism.
In that case:
Q: how did the Italian Mafia Boss burn his lasagna?
A: ah, he forgotaboutit.
