Effectiveness: 4/10
To its credit, this ad would have probably worked on me before its spokesperson killed a white woman to death.

Usefulness: 8/10
I spoofed this ad when I was writing an article on Afghanistan's lunatic national sport, Buzkashi, as seen in Rambo 3. So even though I don't have any need to dress like a cowboy murderer, there's still a happy ending to the story of me and Dingo boots.
