Okay all you comedians... I just so happens that I was in a fly shop last year that had a package of "fake" jungle cock. It was impossible to see the "fake jungle cock" due to the packaging, so I bought one.... a great big, $1.99. When I got home and opened the package, I found they were plastic jungle cock "stickers" on cards. About 50 of them all one size. I never tried them so I don't know if they will work or not.
I was so bummed that I'd lost my $1.99 they are stuck in an container I keep of old stuff... Oh well, the moral of the story? Don't buy fake jungle cock unless you can see through the package!
