I was listening to KABC radio yesterday during the JetBlue incident.
Here was my best attempt at a transcript of the dialog from memory. I
know it sounds like something out of Airplane or Abbot and Costello,
but I did not exaggerate or make anything up, not even the last line.

["R" is the radio host. "F" is the fire dept official.]

R: ...and the fire department has already foamed the runway in
preparation...
F: interrupts We don't foam the runway.
R: You haven't? When are you going to foam the runway?
F: We're not going to do that. We'll have firetrucks with foam ready to
spray on the plane if necessary.
R: So these firetrucks can foam the runway if necessary?
F: No, they're just going to foam the PLANE if necessary.
R: But they're also going to foam the runway too, right?
F: starting to get irritated No, we are NOT foaming the runway.
R: Cuz I was told that you're supposed to foam the runway.
F: We don't do that.
R: Is that a deviation from standard procedure?
F: getting really irritated NO! There's no reason to foam the runway.
We only foam the plane.
R: But not the runway?
F: No, there's no reason to.
R: Why not?
F: We only spray foam when there's a fire. Foam on the runway can cause
more problems like making the plane skid.
R: pause So you're not going to foam the runway?
F: sounding exhausted No.
R: OK, I know I'm testing your patience here. One last time for our
listeners: you are NOT foaming the runway?
F: No, we are not foaming the runway.
R: Hmm, I must have watched too many Bruce Willis movies.
