Jennifer Garner joined Instagram on Sept. 1, and has largely made posts of her humanitarian efforts, involvement with her baby food company and workouts, but a more recent post is filled with laughs.

On Thursday, the 45-year-old actress and mother of three posted a video of herself laughing and talking with slurred speech after a dental appointment while praising a song from the musical "Hamilton."

In the caption of the clip, she wrote, “Throwback Thursday– that time I had dental anesthesia…laughing gas + novocaine (sic) + Hamilton = you’re welcome. ”

The video shows Garner riding in a car and telling someone on the phone that she couldn’t stop crying during a song in Hamilton.

“They said, ‘Are you OK?’ and I said, ‘It’s so beautiful... That musical is so beautiful and so I told them about it,” she said. “They have to see it.”
