Bluffing all-in against a Royal Flush...

...and getting called...

"And your days are just about over. Now that's a hard motherluvin' fact of life, but that's a fact of life your bottom is gonna have to get realistic about. See, this business is filled to the brim with unrealistic motherluvers. Motherluvers who thought their bottoms would age like wine. If you mean it turns to vinegar, it does. If you mean it gets better with age, it don't. Besides, how many fights do you think you got in you anyhow? Two? Boxers don't have an Old Timers Place. You came close but you never made it. And if you were gonna make it, you would have made it before now. Night of the fight, you might feel a slight sting. That's pride making sweet sweet love with you." Marcellus Wallace, edited in italics for the G-rating.

(Sorry, but there isn't a Pulp Fiction thread on Hotcopper so I thought I'd just randomly quote it here. I love that movie.)
