Is that what it is? We don't see our frogs -- only hear them at Spinal Tap levels of volume -- but I have noticed that every year the Mormon Tabernacle Frog Choir rather abruptly shrinks to a lone baritone, who carries on for days or weeks after the rest have gone wherever estivating froggies go...I always assumed that was the frog that couldn't get a date. How nice to think that he or she is minding the tads instead!
