Mac: What happened here, Don?
Flack: This was a truck party gone bad. It's the latest craze in after-hours entertainment. They convert tractor trailers into exclusive nightclubs. Times and locations are spread among the social networks.
Mac: Well, I'm assuming this one didn't start at the bottom of the Hudson.
Jo: I thought the truck was not supposed to move once the party starts.
Flack: It's not.
