The biggest human trafficking scam in history, how do you move a lot of women and children out of their country to different countries where they know no one and no one knows them, where law enforcement won't be alerted to missing people because they're already missing?
Russia invades Ukraine, 5 million women and children refugees. I wonder how many are already in cages or on the block to be sold. Who is going to save them, their men... they're forced to fight off the invading army so nope. The US profits by "loaning" Ukraine weapons and ammo, a lot of countries are in this. A lot of the people who run those countries are in this, not the Presidents or Prime Ministers... the guys in the backrooms that really run things did this.
Business as usual.
In an old comic, Superman once used "super-mathematics" to determine the amount of beans in a jar by knowing the weight of one bean and the weight of the jar. The legitimacy of this power is somewhat questionable; not only is this just simple multiplication, but Superman got the answer wrong by a factor of 10 too high, ignoring the rounding errors.
In a Nancy strip from the '70s, the titular character is staring at a jar full of beans in a store to figure out how many there are. She then gets a flash of insight, and runs into the store to claim the cash prize. How many beans in the jar? None!! (As a wide, final panel depicts the now-empty, tipped-over jar, courtesy of the store's cat.)
An episode of Monk had the title character go to a carnival as part of an investigation with Sharona and Benji. It turned out they were having one of these. Monk tells Benji to guess a certain number (without actually seeing the jellybeans) and he wins. He explains at episode's end that he actually saw the boxes for the jellybeans, multiplied the number of boxes by the normal amount in the box, and subtracted a few to account for the proprietor eating some.
In the Phineas and Ferb episode "We Call It Maze", it's not a contest, but one of the many puzzles in the titular maze made by a computer. The jar was placed next to a door, that would open when the correct number of jellybeans was inputted. While Phineas and Baljeet were debating which units of measure to use to calculate the correct number, Buford gets impatient and opts to eat all the jellybeans and enter "0". It worked, though Baljeet called him out for cheating.
