Proper Cropper

Brooks and Fife were working the bullrushes with minnows and bobbers
I was flinging a wooly bugger with tri-colours
It was early in the season and the cold water had not touched fifty
the fly caught three and lost two
they caught two combined
"What do you call that fly?" Brooks inquired
"It's just a ubiquitous woolly bugger" says I
"Well, seems a proper cropper then" says Brooks
and a fly gets a name..................
