The 84-year-old comedic actress struggles with condom packaging, swears at the camera, and generally has a great old time conveying the message that it's best to adopt spayed and neutered pets from the pound.
Interestingly (or, more likely, deliberately) that's actually the blooper real of the "official" (and much less funny) PSA produced and released simultaneously online.
Cheers, PETA. Please let this be the start of a new brand.

UPDATE: Commenters below have pointed out that the offhand blooper about adopting a dog on your way home is way off message for animal welfare as it seems to encourage impulsive adoptions. I have to agree. So I changed the headline.
