One day, a "non-stop" talking phone salesman called, but I was busy with a customer. I put the phone down and forgot about it. Half hour later, I picked up the phone and that salesman was still giving his talk!
Seriously bh? Wow! Talk about being oblivious that saleman would have to be it! Talking that long without receiving any response? Wow! 

That is amazing. Thank you for your reply! :)
