A lawyer was on his way to court when he saw a sign outside a store that read, "Free legal advice. Just ask inside." Curious, he went into the store and asked the shopkeeper, "I'm a lawyer, what's your legal advice?"
The shopkeeper replied, "If you give a lawyer $500, he'll bill you $1000. If you give him $1000, he'll bill you $2000."
The lawyer laughed and said, "That's funny, but what's your real advice?"
The shopkeeper smiled and said, "My real advice? Never pay a lawyer in advance."
