Mayim Bialik made a subtle return to "Jeopardy!" one year after she was let go from the beloved game show. 

Earlier this week, the former host was referenced in a clue which grabbed viewer’s attention. 

"Jeopardy!" contestant Colleen Kelly chose a $600 clue in the game show category, "TV Coupling." The prompt read, "Sheldon & Amy, pure genius."

Kelly correctly answered, "What is ‘The Big Bang Theory?'"

The 48-year-old actress portrayed neuroscientist Amy Fowler, who was the love interest of Jim Parsons’ Sheldon Cooper on the popular television series from 2010 until 2019. 

"Jeopardy!" fans were quick to comment on the Bialik reference on social media. 

"Always gets me when a Big Bang Theory clue comes up in the post-Mayim era," one viewer wrote on Reddit.

Another comment read, "In a few years, they should do a category when the answers are just all Jeopardy hosts, from Art Fleming, to Mayim Bialik, even George Stephanopoulos."

Bialik’s reference comes one year after she was fired from the popular game show. 

Last December, Bialik announced she had exited from her hosting duties.
