Hey, Ron! I am going to pass you the basketball with 2 seconds left in the game. What's your move?
I only shoot in that situation if I know it is going to go in.
Hey, Ron! I have this lottery ticket but I am leaving the country forever tomorrow because I have been deported. Would you like it?
I only take the lottery ticket if you can guarantee me that I will win.
Hey, Ron! It's the 5th/6th inning and there was a close play involving your baseball team. There's no risk associated with challenging the play other than not being able to challenge another play again if you lose the challenge, which probably won't matter because all plays are subject to review after the 6th inning and the odds of there being an obvious blown call going against your team in the next half inning is not very high. You lose your remaining challenges after each game. What do you say?
Wait, my challenges don't roll over to later games? You're telling me I can't challenge every single play against the Cardinals, even routine flyouts, just for fun?
