It is NOT from Ghostbusters... it's absolutely from They Live...

Ghostbusters has such great quotes as
"oh, Spengler.. are you o.k.?"
"I feel like the floor of a taxi cab."

Or
"Do you want this body?"
"Is this a trick question?"

LOL!!!!

Or
"What floor are we on?"
"Ummm.. Somewhere in the teens."
"Well, let me know when we get to 20. I'm gonna throw up."
