Free Sex Tonight !!!

I asked a Chinese girl for her number. 

She said, "Sex! Sex! Sex! Free sex tonight!" 
I said, "Wow!" 

Then her friend said, "She means 666-3629."

Free Coffee !!

Customer to waiter: Everyday you charge me money for a cup of coffee. How wonderful it would be if you serve me coffee free of cost today.

Waiter: Sir, everyday you drink coffee from a filled cup. How wonderful it would be if you drink from an empty cup today !!
