David Letterman made sure to bring back childhood memories for Sarah Michelle Gellar during her appearance on CBS' Late Show on Tuesday, Oct. 1.
The late-night host cued up an old video from his original late night program on NBC, featuring the actress when she was a little girl.
"You have been on this show when you were a tiny, tiny little kid," Letterman told Gellar. "How old were you when you first were on this show?"
"I think I was 5 or 6," the Buffy the Vampire Slayer alum answered.
