DeLaWho? DeLaWhat? DeLaWhere?

I just picked up the phone and was greeted by the lovely voice of a telemarketer asking for my roommate. I politely asked "May I ask who's calling?" She responded, "This is ____ from the International Readers Club" (or something phony like that). Instead of breaking into my new telemarketer hangup routine, "Wait for it, Wait for it" and hanging up, I said "He's not available." Instead of a gracious thank-you or a somewhat kind good-bye, the woman said "Yeah Yeah" and hung up. I got a good laugh out of that.
