Bill's such a trout; everytime he enters the club he's got a younger chick on his arm...
For years, Salmon swam through all the waters the world had to offer. He had seen oceans and seas, rivers and lakes, ponds and streams; and he had met many fish along the way. However, when he came across this particular fish, in a pond he never would've expected, he was stunned. Never in his wildest, fishy dreams, did he ever imagine he would find a fish as perfect for him, as he was for her. From the moment they first met, he believed in love at first sight, because in his heart he knew, he was her Salmon, and she was his Trout.
A fresh water fish, there are many species of them. Brook Trout, Rainbow Trout, Brown Trout, Tiger Trout, Lake trout, etc. Trout are a very popular game fish and are stocked in waters for Trout Season. Trout are also a very tasty fish which are commonly ate.
