Give American Dad the Sunday night win again. Not as much of a knockout as the last few episodes, but the ending action sequence is easily the funniest thing I saw all night.
The Smiths (minus Steve) are planning to fly out for Haley to visit a university, but Steve accidentally flying one of Stan's military drones into their airspace delays the flight. The delayed flight thing probably would have gone a bit better had South Park not perfected it on Wednesday night.
The actual main plot of Steve taking Stan's drone for a joyride started slow enough, but got really good once Stan came home (because he was dumb enough to get off the plane) and found out it was in the shop. This leads to a fight with the Chinese Mafia atop a float, in which Stan dispatches them all with his CIA skills and tosses them all off. Of course, since the float's going at a leisurely 2 MPH, they're all able to simply walk alongside the float and point their guns. Best sequence of the night.
Enjoy it while you can, because AD's really starting to hit its peak.
