In the movie RED (2010) I heard some phrase I didn't understand at all. So, an armed FBI team is getting ready to attack main characters (MC) who have been taken a guy (TG) to extort some secrets from him. A dialogue following:
- TG: Are you gonna let me talk to them? I can negotiate something.
- MC: Thanks, when we want your help, we'll get out the drain cleaner.
I don't get it at all. Why it's "the" drain cleaner, because it wasn't any before in the movie. I guess this is some kind of joke, bot it seems to hard for me to understand.
