I remember reading an article a LONG time ago where some dudes experimented with taking parts off of a gobbler decoy to see how far it could be stripped down before toms stopped responding to it. Basically, as long as a blue, red, and white head looking thing was in place, turkeys would attack it. The final version that worked was a sock painted like a gobbler's head placed on a broomstick handle. I searched online several times and can't find any reference to the article, but it was in an old hunting magazine...Petersen's, maybe? Anyhow, that article definitely sheds light on how well "the funky" seems to work.
