A favorite in the probability world is calculating the chance of rolling a certain sum with 2 dice (or number cubes- the PC way to say dice). I have always use the game Beano for this purpose but while enjoying Friends one evening Monica and Chandler provided another illustration while playing craps in Vegas. Now, I would never use this example unless my audience was out-of-high school since it involves gambling and deciding to get married based on the sum of two dice. But is does provide an opportunity to discuss what is the probability that Monica rolls a sum of 8 (5/36) or a 'hard' 8 (rolling 2 fours- 1/36).
The clip from the episode is below. Enjoy. And in the words of Monica Geller, "It just got interesting."
