His Head Exploded

"Where do you come from?" asked the frog in the well.
"From the great ocean" replied the other frog
"How big is your ocean?"
"It's gigantic."
"You mean it's about a quarter of the size of my well here?"
"Bigger"
"Bigger? You mean half as big?"
"No, even bigger."
"Is it... as big as this well?"
"There is no comparison."
"Thats impossible! I've got to see this for myself."
They set off together. When the frog from the well saw the ocean, it was such a shock that his head just exploded into pieces.
