Unless you're a jerk like I pretend to be sometimes. If I'm not pressed for time, I've got no problem playing the game and feigning interest just to use up a telemarketer's time. After all, the longer s/he's on the phone with me, the less time they have to annoy someone else in a less playful mood.
