Oh, that's priceless. By the way, I once handled a telemarketing call this way (stop me if you've heard this one):

Me: "Hello?"

Telemarketer: "Good evening m'am, I hope you're well. Now m'am, have you heard about Grade A Canadian Angust beef?"

Me: "Uh...this is a vegetarian household."

Telemarketer: "Oh, I'm so sorry!" ::hangs up::
