Most I get these days are very bad AI trying to get me to say "yes" (this is recorded and used to try to scam access to your private stuff on line). Since they are recorded, I like to use a demonic voice and tell them "Thank you for calling the United Church of Satan...all our operators are busy...if you wish to sell your soul to the devil, press one now...if not, please wait for the next availble operator...Satan bless you..."
I've had "changes in medicare", "your recent car accident", pre paid burials, car warranties, and the occassional "your social security number is (insert whatever here"calls 24/7. I have gotten human operators (most with Hindi accents) who just come right out and say "Let's just make this short and give me your bank account information or (insert threat here)"
