Just make up a random story. It doesn't have to make any sense what so ever.
Heres mine
in 1600 there was a guy who liked da sound of da dropping water so he was all like "ima go make some shit and see if it makes sounds". so that guy made some shit and the shit looked like rubber bands, but only bigger. So after he perfected the art of playing da rubber band like a baws and not like a potato, he made flyers for his Big Rubber Band group, and got some people to join. There were 3 ppl that joined, Bobby, Cumlyuna, and Kuntbaws.They all sucked dick at playing da big rubber bands, but they were like "we gotta play da concert", and so they asked the big music people if they could have a cool concert, but the big music people said "nu you cant hab da concert cuz u suk ass". So they got all da peeps in town and they had a big speech which said "people of uglyville, we must band together and play da concert and teach da big music people how 2 dougie". (even though the dougie wasnt invented back then) so they got all da big rubber bands and all da people of dickville, and the walked to the big music peeps house while they played da big rubber band. Then the big music peeps said "WE CANT TAKE IT ANYMOAR U BISHES SO STFU AND WE ILL MAK U A BAND AND U CAN PLEY DA CONCERT." and the big rubber band group were happy. but they didnt want to play the concert no moar. They wanted to play da marching concert. So they got thuh ppl of suckville and they all march in da marching concert. And thats how the kittens learned to eat disks..
