I've been known to do similar things... Especially when it's clear they're just reading from a script and don't have a clue, and have either paused at the wrong point or misread something. If I'm not in the mood to play... I listen long enough to find out it's a sales call (the Do Not Call Registry doesn't stop political calls, certain fund raisers, and calls from places you do business with, like a bank or credit card company), and I say "No thank you, goodbye" and hang up.I've been known to make up random sentences as responses to annoying questions. Nothing like having a salesperson thinking you're whacko to get them running from you."
"Space Aliens just don't like peanut butter"
"Why doesn't my auto mechanic sell spinach?"
"Did you know I can count to 1000 in twelve languages? Let me show you. OK. First one is English. One, two, three, four, five, six..."
"I'm under the Atlantic Ocean right now in a secret bubble!"
"Why aren't forests purple? Green is boring."
One that pisses me off significantly is when I get donation solicitations for various police "supporter" programs. I don't do donations in response to calls like that in the first place; with very, very few exceptions, too little of the money raised goes to the actual purpose. But when I've never heard of the association or group in question -- and I'm a cop supposedly being served by them! -- They don't get a dime.
