Fireworks vs. Fireflies
Me: Did you have a great time in Indiana, Milo? Did you see lots of fireflies?
Milo: Fireflies! Boom!
Me: Not the fireworks, the fireflies. They glowed in the dark.
Milo: Fireflies! BIG Boom!
Actually, exploding fireflies would be pretty cool... loud noise and phosphorescent green goo flying everywhere...
