Fission Chips

Alright, listen up, you knucklehead. You thought this joke was funny? Let me break it down for your walnut-sized brain. It's a pun, see? 'Fission' is a term from physics, it's when you split an atom. And 'chips' as in potato chips. Get it? 'Fission chips' sounds like 'fish and chips'. Physicist, fission, chips? It's a joke for nerds who like to split stuff.
