Later in the day, the other frog ate a fly and the two frogs burst out in laughter. As time went on, the frogs enjoyed the flies so much that the sight of a fly would cause them to double up with pleasure (if it's possible for frogs to double up!). But of course, the most pleasure came when the fly was actually eaten.
A third frog hopped up to the first two and asked what was so funny. The first frog answered "Time." "Huh?" asked the third frog. The second frog explained:
"Time's fun when you're having flies."
