The Foremost Threesomes of Pasadena - 7x7 π

Cryptic Mini #000000081: "The Foremost Threesomes of Pasadena" obscuration level: π (you'll laugh, you'll cry, you'll π€) Happy leap day to all, and happy 12th birthday to Ja Rule! I wish I had had the foresight to write a clue in his honor. Oh well, I'll do it next year in 2028!
