all about flies

Customer : Waiter, there's a dead beetle in my soup. Waiter : Yes sir, they are not very good swimmers. Customer : Waiter, there's a fly in my soup. Waiter : That's all right sir, he won't drink much. Customer : Waiter, there's a fly swimming in my soup. Waiter : So what do you expect me to do, call a lifeguard? Customer : Waiter, what's the meaning of this fly in my tea up? Waiter : I wouldn't know sir, I'm a waiter, not a fortune teller. Customer : Waiter, this soup tastes funny. Waiter : Funny? But then why aren't you laughing?
