I enjoyed this episode quite a bit, even if it did not reach the same level as the previous one for me. What I liked most is that TBBT finally lets Sheldon's insecurity sit at the centre of the story instead of hiding it behind arrogance and one-liners.
The funniest parts come from watching Sheldon completely unravel once he feels intellectually threatened. Jim Parsons plays the panic and jealousy perfectly, especially because Sheldon still behaves like he is the smartest person in every room even while clearly losing control.
I also really liked how the group backs Sheldon up despite all his behaviour. That friendship dynamic gives the episode a surprisingly warm edge underneath the comedy. And honestly, the Dennis pranks were just genuinely funny throughout.
A solid and very enjoyable 7.5/10 for me.
