Agent Archangel has alerted us to further penetration of Area 51 into popular culture. Area 51 porn! It's only soft porn, shown on late night Cinemax, but it's a start!
Here's the only known review of "Areola 51". Apparently the aliens have a certain fascination for female nipples. (Who wouldn't travel the galaxy for some good titties?)
Don't expect this one at a Red Box near you, but you might catch it again on Cinemax.
Archangal notes that there is also an Austin-based band of the same name: Areola 51.
