Young Sheldon, “Senior-bazinga-itis”

The Young Sheldon is excited for his senior year, but his ego takes a big hit when he discovers that the new kid Young Larry is, perhaps, even smarter at physics than he is! As the two compete for the affection of their teacher, they accidentally create a time vortex that transports them all the way back to the year 1975. Enlisting the help of a young Carl Sagan, the two bond as they not only work out how to get back to their own time, but also how to grow back all of Young Larry’s skin. (Carl Sagan guest stars as himself, using the power of archived footage, artificial intelligence, and computer graphics technology.)
