A small boy says to his father "Dad, what's the
difference between 'theoretically' and 'realistically'?"

His dad thinks and then says "Right-ho son, go and
ask your mother if she'd sleep with Wayne Rooney for a million quid."

The boy toddles off and comes back saying "Dad,
dad, she said she would! She would sleep with Wayne Rooney for a
million pounds."

"OK son," says his dad. "Now go and ask your
sister the same question."

The boy toddles off, and comes back saying "Dad,
dad, she said she would too!"

So then his dad says "Right, son, now go and ask
your brother if he'd sleep with Wayne Rooney for a million pounds."

The son comes back excitedly saying "Dad! Dad! He
said he would too!"

"Well there you have it, son," said his dad.
Theoretically we could be sitting on three million quid. Realistically
we're living with two tarts and a poof."
