Penny: Uh, that doesn't sound good.
Sheldon Cooper: Remember the old days when I used to point out that your check engine light was on?
Penny: Yes.
Sheldon Cooper: Well, we're ready to stroll down memory lane. Penny your check engine light is on.
Penny: Yes, I know it's on Sheldon. Oh, no, no, no, no. I can't afford this right now.
Sheldon Cooper: Maybe it's just something minor. Oh good news. The light just went out.
