Anvils instead of pianos

Okay so here's the deal, I was contemplating using an Anvil in today's comic but then I figured that people these days don't actually know what an anvil is do they? To be quite honest I myself didn't find out what anvils were used for until I was like 12, I kept thinking they are just this invention for comedies and comics that is just a heavy hunk of metal to fall on people's heads, turns out they aren't!
