Young Sheldon's Season 6 Premiere Included An Unexpected Big Bang Theory Callback

Season 2, Episode 9 ("The White Asparagus Triangulation") of "Big Bang Theory" features a hilarious scene when Sheldon tracked down Stephanie (Sara Rue) and Leonard (Johnny Galecki) at a movie. It's impossible not to laugh as Sheldon moves from seat to seat, making loud, strange noises in an attempt to find the seat with the "acoustic sweet spot." Viewers were happily surprised when "Young Sheldon" made a reference to the acoustic sweet spot in the Season 6 premiere.

As Mary Cooper (Zoe Perry), Missy (Raegan Revord), and Sheldon find their seats in church, Sheldon complains that they don't normally sit there, and "This is nowhere near the acoustic sweet spot." Missy quickly shushes him, but it's clear that Sheldon is bothered as he keeps taking turns covering his ears, trying to improve the acoustics. While this scene was a small portion of an eventful episode that consisted of George (Lance Barber) bailing Georgie (Montana Jordan) and Meemaw (Annie Potts) out of jail in Mexico, executive producer Steve Holland enjoyed adding this callback to the episode, telling TV Line, "His love for finding the acoustic sweet spot dates back to his childhood!"

Now that Sheldon is growing up and approaching his teen years — and we know that there's an impending tragedy — viewers should expect to see a lot more Sheldon-isms in future episodes.
