An old man is selling watermelons…

His pricelist reads: 1 for $3, 3 for $10 A young man stops by and asks to buy one watermelon. “That’d be 3 dollars”, says the old man. The young man then buys another one, and another one, paying $3 for each. As the young man is walking away, he turns around, grins, and says, “Hey old man, do you realize I just bought three watermelons for only $9? Maybe business is not your thing.” The old man smiles and mumbles to himself, “People are funny. Every time they buy three watermelons instead of one, yet they keep trying to teach me how to do business…” EDIT: my first gold :O Thansk!

There’s a fried chicken place near me that does exactly this. It’s something like “10 piece for $8. 20 piece for $18.” Everyone who sees that sign thinks they “outsmarted” the system by purchasing 2x 10-piece meals. I’m just smiling, knowing that it’s not an oversight, and a whole lot of people are buying 2 meals when 1 is plenty.


When I was in highschool they used to do pizza sales for fundraisers. A buck a slice or 10 for the whole pizza. A pizza had 8 slices. Turns out the extra 2 bucks was for the box because they made me carry 8 slices on two paper plates.


A farmer has transported his watermelons to a roadside stand to sell. At the end of the day there are a couple hundred left and he isn’t looking forward to the tedious process of loading them back on the truck, taking them back to the farm, then reversing the process the next morning. He comes up with a labor-saving solution: Next to the bin where his melons are carefully arranged he places a large sign saying, “ONE OF THESE IS POISONED.” Reassured, he goes home to sleep. – In the morning he comes back to find that someone has written on his sign, “Now there are two.”


The good ol’ trick of intentionally introducing an inferior alternative to fool us because it’s easier to think in relative terms. Dan Ariely covers this topic in detail in his book ‘Predictably Irrational’.
