Math joke

A mathematician and an engineer were lost in a jungle and found a mango tree and a guava tree. The engineer climbed the mango tree, picked up the mango, and climbed back down. Then, the mathematician climbed the guava tree, picked up the guava and climbed down, then climbed the mango tree to put the guava high in the mango tree's branches. The mathematician then climbed down with a large smile on his face. "Why did you do that?" the engineer asked. The mathematician said, "Now we've reduced it to a problem we know how to solve!"

didn't that come from an aops textbook
