Maybe it's because I just watched the latest episode of Breaking Bad, but something compelled me to do an image search with the words: drug smuggling truck.

Found at 9gag.com. "Gag" in the URL might be a tip off.
Meanwhile, here is a link the search pulled up that has lots of innovative smuggling images. Oddarena.com.
