Third son was looking quite thoughtfully at his jelly beans, giving them a very cautious poke with one finger, he must have been around 4-ish. After being hunkered for quite a long while, he finally gave up puzzling it out on his own and asked, "What kind of poop is this?"
Causing the eldest to shout, "It's EASTER BUNNY POOP!!!!"
"Oh!" said third son, who began to dig right into his jelly beans.
