The Man and the Waiter

Ok this is a joke that requires the skill of reading comprehension and connecting themes.

A man walks into a restaurant and orders soup.

A few minutes later...

The waiter brings the soup back and gives it to the man.

The man says "waiter, taste this soup".
"What's wrong with it", says the waiter.
"Just taste it", the man says.
"whats wrong with it?" the waiter asks impatiently.
"Just taste it!" the man exclaims

Finally, the waiter has had enough and says, "Fine fine i'll taste it. Where's the spoon?"
