All South Park Hidden Aliens

There's been many alien sightings since the first episode of South park aired on August 13th, 1997.

The first episode of South Park was about the portly character Eric Cartman getting abducted by "visitors" who planted a radio dish in him and anally probed him. He thought it was all a dream, but it was not.

Since that first episode, South Park has blown up, and the aliens visiting them haven't gone away. In fact, they are hidden in many episodes as Easter eggs. No surprise, the animators have decided to draw the images of the aliens as the popular grey aliens. You can learn about them here.

I'm going to try and list all of the South Park hidden alien Easter eggs with pictures and video when possible in order of air date.
