When I answered, I heard a clamor of chatter in the background--it was obviously a call center of some sort--then a guy came on and asked for a relative who lives with me. I told him he wasn't here. Then the caller asked, a couple different ways, in a sarcastic tone of voice, whether I "could be trusted" to relay a message to him. Ticked off by his attitude, I said, "You don't have any control over whether I relay it or not, so why don't you just give me the message?" He replied, "Testicles, that's the message," and then hung up.
