The Big Bang Theory went out on top Thursday night, with a series finale that drew 18 million total viewers, the show’s biggest audience since September 2015, and a 3.2 rating in the adults 18-49 demo.

CBS projects that the hourlong episode’s audience will grow to 24.8 million in live-plus-7 ratings.

The finale also boosted the ratings for the season finale of Young Sheldon, which will take over Big Bang’s Thursday 8 p.m. time slot next season.
