12 polar bears and 18 of them want to have a birthday party. That means that 6 of them want to have a birthday party, but they can't because they're dead. Tragic. 12 blu ray disks will mean one disk for every polar bear that isn't dead yet, so that would just mean a variable of 12 polar bears. (or blu ray disks.) Ben Franklin was born in 1706, and the Declaration of Independence was signed in 1776. That means that Ben was 70 years old when he signed it. Adding 12 (number of polar bears with blu ray disks) to that gets us to 82, so the perpetual motion of the salsa is 82. Thank you, I'll be here all week!
