Carl has installed an ultra high-tech security system to keep the Aqua Teens out of his pool. The major problem is the light beams used with the security system- they're so bright that not only can Frylock not sleep, but they can also be seen from space (which Carl said the guy who sold it to them was guaranteed to happen).
Meantime, in space, a pair of alien fraternity brothers named DP and Skeeter have crashed into the Plutonians' ship after going on a drunken joyride through space in their own ship. With a fraternity pledge in tow, they decide to head down to Earth after they spot Carl's security system. Again, DP crashes the ship. When he gets out, he immediately begins wanting to pick a fight with Carl but Skeeter calms him down. DP then tries to hit on both Frylock and Meatwad (causing Master Shake to question his sexuality for the remainder of the episode to Meatwad's anger) before vomiting and passing out on the Aqua Teens' front lawn. Skeeter bolts, leaving DP and the pledge (who they named "Ass Head") on Earth.
When DP wakes up the next morning he and Shake decide to drink a little more but Shake quickly becomes drunk off of very little beer. Frylock tries to get Skeeter to take DP home, but Skeeter tricks Frylock into giving him a ride. DP doesn't make it home, and is instead obliterated by lasers from Carl's security system.
The episode ends as the Plutonians return to their ship and are sucked into space through the hole the frat boys made.
