Jack, Jack, Jack! What a name, what a concept. Consider the knave in the deck of playing cards, he's Jack, located just above the ten card and underneath the queen; a justifiably judgmental place to be. Is Jack jolly or is he jealous of the king? Maybe he's actually aces at the game of jacks. What a card. Beats being a lumberjack or a jack hammer or a car jack. I'd like to hijack old Jack for a joyous jubilee. Jack, be nimble and quick! What a joke! Jack.
