The basketball to some extent apart, this was extremely weak. Going back to essentially catch phrases - "I'm not crazy, my mother had me tested", for example, and in this case "rock paper scissors lizard spock" - not once but three times - is a sure sign that the writers are running/have run out of ideas.
Not as bad as last week, which was one of the worst episode in what has been a very disappointing series, but I am so, so sick of Amy. She's not remotely funny, just relentlessly annoying, and Raj & Howard are rarely funny now, either. Howard has barely had a good line since he hooked up with Bernadette.
After the weak start to series 2, this came back with a vengeance, but all of this series and a lot of series 4 have been pitifully poor. It desperately needs the writers to find a new gear, and to really shake up the show, which I'm afraid is currently in "jumped the shark" territory.
