Michelle Tanner just loves her Uncle Jesse!

John Stamos took to Instagram on Thursday, March 10 to share another adorable throwback video of his former Full House costars Mary-Kate Olsen and Ashley Olsen — and it's so cute to see the twins in the behind the scenes clip!

"'Say my name,' #StamosHomeMovies #FullerHouse #MKAshley #TBT," the 52-year-old actor captioned the video of the siblings — who were just three-years-old at the time! — taking turns repeating his onscreen name back in August 1989.
