Homer has with him Baby Maggie, his dog, and a jar of poisons that look like delicious candy. (Homer: Oh, why did I take my baby and my dog with me when I went to buy poison! And why do the poison has to look so delicious!?) He needs to get all three across the river. He can only take one of them at a time in his rowboat. He can't leave Maggie with the poison. He can't leave the dog with the poison. (He CAN leave Maggie and the dog.) How does he do this?
The Simpsons has had lots of math on it. There is a webpage of all math on The Simpsons here, though it doesn't have last night's episode yet (quite reasonable--- if you expect that then you expect to much from the digital age).
How does The Simpsons compares to Numb3rs in terms of the accuracy of the math presented? I suspect The Simpsons is more accurate; but, to be fair, they don't have to find some goofy math way to solve a crime every week. The math on Numb3rs, goofy as it sometimes is, does connect to some math of interest, see this web page.
