We'll take things that make you smile for $200.
Here's the clue: This actor, author and neuroscientist was the childhood celebrity crush of a contestant on the game show she currently hosts.
If you said, "Who is Mayim Bialik," you get to select the next clue.
In what might be the most adorable contestant introduction ever, the aforementioned crush was an actual topic of conversation during Wednesday's High School Reunion Tournament.
While introducing contestant Dan Oxman of South Orange, New Jersey, Bialik giggled:
"I don't really want to talk about what we're going to talk about, but apparently I was your celebrity crush growing up?"
Oxman, now a senior in college, replied:
"This is a long time ago, Mayim, but you know, when I was a little kid, I saw you on TV and I really admired how you played, like, a super awesome scientist [on 'The Big Bang Theory]."
"And then I found out you were a scientist with a doctorate in real life. And then I was just like..."
The grinning contestant made a "mind blown" noise before adding:
"And you haven't aged a day."
You can watch the moment below.
Viewers of the introduction had all kinds of reactions.
Of course, the majority agreed the moment was adorable.
And others related to Oxman's admission.
But some - like us - felt a little old, considering our childhood featured Bialik as a different character.
While Oxman ended up in third place, he did walk away with $1,662. Plus, he spent a good half hour with his childhood celebrity crush - we'd call that a win.
