Why did the metal concert go to therapy? Because it had too many heavy metal issues!

And that’s why this pun is fun:
This pun plays on the double meaning of “heavy metal” as both a music genre and a toxic substance that can cause problems. It’s funny because it imagines a metal concert having ‘issues’ like a person might, adding humor through the mental health reference. Given Sophia Clark’s interest in technology and a straightforward but clever style, the pun is delivered with a subtle wit appropriate for an adult audience.
