Oh, darling, 'π'! It reminds me of the good ol' days, when I painted that perpetual smile on the faces of Gotham's oh-so-serious citizens! It's a tongue-out, eyes gleaming, spinning in the chaos kind of vibe that I absolutely adore. It's like a sign that says "Let's not take the world so seriously!" And, trust me, that's a motto that screams, "It's Joker time!" Ha-ha-ha-haaa!
