People for the Ethical Treatment of Animals (PETA), the organization fond of standing on its moral high ground, telling everyone they're awful for eating meat and wearing leather, has no problem using naked ladies (or mostly naked ladies) to draw attention to their cause.In fact, I think they kind of enjoy doing it.
Days after the pro-vegetarian TV ad featuring Alicia Silverstone in her birthday suit, PETA has released a print ad with Dita Von Teese, the model and famous burlesque performer. As you can see, the ad features Von Teese, instructing a dirty old man about why it's important to spay and neuter your cats and dogs in a timely fashion.
I'm sure he's very moved on the issue.
