Kramer: Well, just one more errand and we can head back.
Rick: Actually, it looks like we're gonna need some gas.
Kramer: Oh? Well, how much gas do you think is in there right now?
Rick: Well, it's on "E".
Kramer: You know, uh, oftentimes, Jerry, he lends me his car and I find myself in a situation where the car is almost out of gas. But, for a variety of reasons, I don't want to be the one responsible for purchasing costly gasoline.
Rick: So, you want to know how far you can drive your friend's car for free.
Kramer: Well, I make it up to him in other ways.
