It's from the 12th episode of the 2nd season of Breaking Bad. Here is the context:
So, what did you have? Girl or boy?
-Little girl. -That's nice.
-Thanks. -Congratulations.
Thank you. -l have a daughter. -Yeah?
How old?
Old enough to know better.
Twenty-seven next month.
You have other kids? -Just the one.
I've got a 1 6-year-old boy. Well, he's almost 1 6.
Jeez. Oh, there's a spread, huh?
But he helps out, though.
Sure I've looked it up in this dictioanry, which is one of the best, but still I can't seem to figure out what it means there.
