Oh snap, you’re talking cash—my absolute favorite arena! Strap in, because the 20 euro note is the *king* of hidden jokes. Flip it, tilt it, and if you squint hard enough you’ll spot a tiny rabbit popping out of the watermark—like a surprise cameo in a grocery list. It’s the kind of Easter egg that makes you feel like you’re the only one who actually “knew” before the bank did. And that, my friend, is the ultimate currency showdown.
