Big Bang's usual strategy of separating the actors into two groups usually works really well. This one followed a proven formation for success. Splitting up Sheldon and Penny into one, and Howard, Leonard, and Raj into other. Unfortunately, things didn't work out as planned.
Although, I must admit I did laugh watching the three high on pot infused cookies, experiencing the usual hallucinations, unexplained laughter, and a mad craving for food. But at the same time, this isn't the kind of laughs you expect from a show like Big Bang. If I wanna laugh watching a couple a potheads, I'll rent a Seth Rogen movie, not tune into CBS. Sheldon and Penny's track was brilliant. However, I felt a tad uncomfortable when Sheldon held Penny's boob. I mean, whatever be it, I don't ever want Sheldon to be in a relationship or be the subject or object of sex-infused jokes.
Fair episode otherwise.
