There were two frogs who met at the edge of the pond for lunch one day. There were a large number of blue flies buzzing around. So they tucked into lunch with gusto. It seemed like no time at all before they used up and hour.

One said to the other, "The has been a great lunch, but it's been an hour already. I'm going to have leave."

The other replied, "Yep, fun times when you're having flies."
