Jennifer Aniston and Mayim Bialik appear in a recently posted throwback picture. The two girls are in Mayim Bialik’s bedroom–and they’re both really young.

Not everyone knows that before Jennifer Aniston hit her fame and fortune as Rachel Green on Friends, she starred with Bialik in a show called Molloy. It was even back before Mayim Bialik became a star on Blossom.

“Yes this is me and Jennifer Aniston in my childhood bedroom. We did a show together before I did “Blossom.” #tbt !!!” the Big Bang Theory star captioned the photo on Thursday.

While both ladies have grown up a lot since this photo was taken, there’s no mistaking either Jennifer Aniston or Mayim Bialik in the shot. They both have very unique physical characteristics that are still easy to recognize today.

Molloy was only on TV for seven episodes back in 1990, airing on the Fox network. Mayim Bialik played a very grown-up 11-year-old forced to move in with her bratty stepsister–Jennifer Aniston–when her dad remarried.

Fans are no doubt enjoying a few laughs after seeing this throwback picture–at both Jennifer Aniston and Mayim Bialik’s expense.
