Bob's Burgers

Two men go to China on vacation, and they find out about a food eating competition. They decide to register for it online, but find out in a reply message that the contest has been challenged due to lack of entrants. They go to a nearby restaurant to eat instead.

"Damn", one of the men says, "Now I will never impress anyone here with how much I can eat".

"Yes you will", the other man says, "right after you finish the three burgers you just ordered for yourself.".
