This was hilarious. The Penny-Sheldon tutoring storyline was great to see again – their odd bonding and Sheldon's over-the-top teaching style delivered some of the best laughs. It felt fresh and true to both characters. The gorilla experiment tied everything together without feeling forced.
The Howard-Bernadette arc also progressed nicely with its ups and downs, and the humour around their relationship was spot-on.
8.5/10: Overall the episode had strong character moments, solid jokes, and good pacing. One of the stronger ones this season.
