That's Rowdy Roddy Piper, speaking in They Live.
It could have been a much better movie except they sacrificed a plot that could have made sense for action scenes that don't. For example....
Let's say you got your hands on a crate that someone else has risked his life for. All you find in there are dozens of sunglasses, which makes no sense. So you take one and discard the rest. But when you try on the shades, suddenly, you can see the evil alien overlords and the subliminal messages they have been putting out to control you. Do you....
a) immediately go back and retrieve the crate? Or....
b) Rush into the nearest bank, pull out a big gun, say your stupid line about bubble gum, and go back for the crate only a few days later, only to discover the garbageman has come by?
If you answered (a), chances are you will survive the alien invasion. If you answered (b), there is no hope for you.
The fact that the movie says that violence is the only possible solution shows that this film is emitting a few subliminal messages of its own. I'd be curious to see what They Live would reveal if watched with They Live-type sunglasses.
And now for the next quote in the film quote game. Tthe last time I did a quote, nobody got it for a full week. So this time I'll give you TWO BIG HINTS.
1) You already know I like the film classics.
2) It's famous as the FIRST-EVER line spoken in a film by a certain WELL-KNOWN celebrity.
"Gif me a visky, ginger ale on the side, and don' be stingy, baby."
