Only three stretchy frogs left in the whole of Walmart, the biggest retail corporation in the entire global world?

Sounds like someone else has already separately reached the same conclusion as to their transformative value, Stephanie.

A little like Leibniz and Newton both inventing calculus, but on a grander, more colourful and more amphibian scale.

Of the two 17th-century polymaths, which would be more likely to have placed plastic frogs at the end of their lap lane, had they been invented, I wonder?

You'd think that Newton would be the fave, what with his playful apple-juggling reputation.

But then Leibniz was the cheery optimist - 'best of all possible worlds' and all that.

Although that would perhaps mean that his grey lap lane terminus wouldn't need cheering up. In fact, he might have seen it as sacrilegious even to consider it.

All in all, I reckon Newton wins.

You're in good company! Make sure you remove the curly wig before diving in. Prone to drag, waterlogging and rotting, I suspect. And could clog the pool filters with talcum.
