Yes. But these guys didn't.
This video's title "Jeep vs. Pool" sort of implies that these guys were attempting to driver over the top of the water like some kind of Jesus Jeep. They end up driving into the pool rather than over it, but they don't seem to mind.
That said, it is entirely possible to driver a Jeep over a body of water, you just need a couple hundred extra horsepower and paddle boat tires to do it. Let these Icelandic hoons show the Canadians how it's done.
