That guy's reaction when Kofi kicked the table.
Also, kayfabe-wise, why was that guy just sitting in his car in the middle of the parking lot? What's he waiting for? Either way, it made for a pretty entertaining ADR/Big Show segment.
Speaking of Del Rio, his match with Ziggler was great.
And Jack Swagger returning doesn't really do much for me. The guy can wrestle, but hopefully he improves on the mic. Could also get a new gimmick as well. Perhaps a heel coach character that forces faces to go through extraneous stuff like 100 pushups so that they get too tired to wrestle and lose a match or something. Just a thought.
Overall, a decently good Smackdown.
