If you got Joe Manganiello or Steven Moyer from "True Blood" to smoke a pipe you'd probably drive up sales pretty significantly. I think the way to kill sales is to have the women from "The View" or Hoda and Kathy Lee advocate it.
+1 winton.
I'd have to say that Kevin Costner as Devil Anse, and Robert Downey Jr. Have already done quite a bit for the piping community, as did the whole LOTR cast! If some of these guys actually did take it up, outside of acting, it would definitely boost piping and our cause!
Denis Leary, if you could get him to smoke a pipe and turn into a gentleman (dress nice, groom, speak like one), I guarantee you the entire world will talk about it.
In the meantime, I will show you a skit he did on his opinions of how low the coffee industry has sunken. When I ask for black coffee with nothing in it and get people looking at me like I have two heads (you mean people drink it that way?) I can definitely relate to his sentiment.
