You never know when you might find yourself stranded on a desert island, by choice or otherwise, and as every castaway movie has taught us there are coconuts a-plenty on desert isles.
Coconuts can be eaten, worn as a bikini and used to simulate the sound of horses galloping, but first the husk must be removed before the coconut can be cracked open, which is really hard to do without tools.
Enter "The King of Random" Grant Thompson with a time tested method for de-husking coconuts while using as little energy as possible- by dropping a giant rock on it.
Once you're done dropping rocks on husked coconuts and dropping unhusked coconuts on sharp rocks you can use the fibers to make rope, which is another handy thing to have when you're a castaway.

But with the way math is taught in most schools now, the closest most get to pure math is a proof-centric geometry course (which some like much more than a cookbook algebra course), and those that trying to go more heavily into math in university hit a wall with an abstract algebra course that weeds out a large number of people from math programs.
