Do the math. (Na) x 16 + Bat + Man = The catchiest theme song in history.
This shirt is the ultimate inside joke for math geeks, chemistry nerds, and caped crusader fans. We've taken the most iconic intro in TV history and boiled it down to a simple, brilliant equation. It’s minimalist, clever, and guaranteed to get a laugh from anyone who grew up watching the dynamic duo fight crime in technicolor.
Forget the cape—sometimes you just need the right formula to be the hero.
The Specs:
- The Math: (Na) to the power of 16 (The classic "Na Na Na…" chant).
- The Graphic: Vintage-style Bat symbol and figure icon.
- The Fit: Classic unisex cut, perfect for the lab or the comic shop.
