Next to the Parking Spot Escalation, this is one of my favorite episodes of the season. Both the main plot (Howard meeting Amy's parents) and the side plot (Sheldon taking care of Amy) were excellently done. The ending of the main plot was resonating and satisfying, while the ending of the side plot was laugh out loud hilarious. It wasn't an episode that profoundly affected the plot of the series, but it was a creative diversion that I liked a lot.
