Fishing With A Mirror

I used to know this old Cajun by the name of Jacques.  I don't think I ever knew his last name; but it ain't important...

Anyhow, one day, Jacques, he decide he gonna have a little fun while he's fishing; so he sets up this big mirror in the bow of his boat and ties it good.

Well, he's sittin' out in the middle of the lake, fishing; and this boat pulls up a little ways away..."Is that a mirror in the bow of your boat?".

"Sho' is."

"What you doing with it there?".

"Fishin'.".

"You fishing with a mirror?".

"Dang right!".

"How many you done caught with it today?".

"You the fifth one, today, I garontee!".

Many thanks to Mr. Justin Wilson.  You got it right, my friend, 'I garontee'.
