Hehe, I just got one in Sharkhead Island. I was flying to my mission and was coming down to the door and passed over a group of Family and Arachnos and the Arachnos boss says:
"I have a weapon pointed at a man's head and I'm in the middle of an interrogation. Did it ever occur to you that MAYBE trotting past like an elephant could be considered an intrusion?"
I actually stopped for a minute to laugh at it.
