The Vader was a present from my parents when they went to NYC. It can say "You don't know the powah of the Dark Side" and also it can breathe very loudly, just like Vader does.
The machete is real, I bought it during some vacations in Punta Cana, but don't fear: it is not very sharp.
When I saw the picture with all those things, I though: "ok, but nobody is going to notice that".
