Last week I met this guy who asked me for my number. I told him that I will tell him only if he answers one of my questions first. He agreed.
"What is the one thing common between China, North Korea and former Russia?".
"Communism"
"Are you sure?"
"No, fingers crossed!"
"Oh well. That's correct! My number is 555-0112. Call me."
"Hey wait! what's your name?"
I punched him in the face (p.s. very gently).
"There, I told you my name"
