Nope haven't seen it, but I've seen "They Live", an old John Carpenter movie about aliens taking over the planet disguised as humans. Here's a memorable quote from when the main character, armed to the teeth, enters a bank and notices (using his special shades) that most people are actually aliens :
"I came here to chew gum and kick ass... and I'm all out of bubble-gum!"
aha

The fucking Goonies are good enough for me! Didn't you want to be a Goonie when you saw that movie?

Really...? Have you read The Last Samurai?

I saw someone mention the Goonies, awesome! I remember watching that as a kid, great movie. Damn, now I have the urge to see it. Hopefully its out on DVD, time to check NetFlix... :D

Boobie trap! Dats what I said!

The Goonies was good when I was a kid, terrible when I saw it as an adult. Kind of like Thundercats.

Das Boot was pretty good too.

HHHEEEEYYY YOOUUUU GUUUUUUYYYSS!
