The squirrel in question is actually a trained animal known as Twiggy the Water-Skiing Squirrel. The first Twiggy began performing in the late 1970s, and since then there have been several squirrels who've used the name. Twiggy has since appeared on various TV shows and in films such as Anchorman.

Oh Paisley's there, too, alongside his band, all of them picking and grinning while half-submerged (drums and steel guitar, too) in murky river water. And joining them are plenty of attractive folks splashing about on tubes, jumping off boats and sunning themselves on the dock. When Paisley sings in the song that he and his friends are "laughing all the way to the river bank," he obviously takes that lyric seriously. This is one nutty riverside party.
