I used to do that a few years ago...it started when one of my friends called me, and some lady saying

"Thanks for last night, I hope you arent hurting today. ****er!"

Then my dad and I tried one on my mom, where we even got the lady who says the words to say "I apologize, but I have to read this word for word." I forgot exactly what it was, but it was pretty funny how confused she was.
