Wow, you put a lot of thought into these things don't you? You started planning this thread like 4 days ago.
With a baseball bat and a glass of water
Uploading a computer viris into the mothership
Board with a nail through it
A nuke down a bug hole
We didn't do anything, they just caught the flu
With a trail of Reese's Pieces
A Christ-like fifth element
Oh wait, we were on Earth all along
Nuke it from Orbit, it's the only way to be sure.
"Ooo, piece of candy. Ooo, piece of candy. Ooo, piece of candy."
