Olympians as DJs

Listen up, buttercup! This joke is about Olympians, those super-athletes who compete in the Olympics. The punchline is that they are bad DJs because they keep "breaking records." Get it? Like, sports records AND music records? It's a play on words! And don't feel bad about not getting it; you probably think a 'vinyl' is what they use to make those shiny gym floors, you Neanderthal.
