Seafood joke!

In a biology class the teacher asks, "Can anyone tell me why a flounder
is flat."
Little johnny raises his hand, "I know, I know."
"Go ahead Johnny."
"My uncle told me it's because a whale raped the flounder."
"That's terrible Johnny.  I'll have to speak to your parents.  Let's try
another one."
Why does a lobster's eyes protrude from its head?"
Again Johnny raised his hand.
"We'll give you another chance."
"My uncle said when the whale raped the flounder, the lobster saw it."
