How often does this exact scenario happen
Doctor: "When was your last BM?"
Patient: "You mean the last time I took a shXt?"
All of my gf's in Sicily used to call my cars B-M-Vu's. "Vu" means "V" in Italian so I always replied with "Doppo Vu" which means "double V" or W in Italian. And I always made a serious face when I said it, as if it gave the car some sort of extra prestige. "Non Vu... Doppo Vu." Kinda like "Bond... James Bond."
