Seriously? OMG! WTF?

Lee Aronsohn, the co-creator of Two and a Half Men Tweeted the above picture from the set and asked, “Wednesday runthru w @aplusk. Guess what the scene’s about.” It is all too blurry for me to figure it out, so what do you think it is about?
Who else is getting so excited to see what 2.5 2.0 is all about when it comes back to CBS September 19th at 9p?
