LOL! This Video Of Jennifer Garner On Laughing Gas Will Have You In Stitches

Jennifer Garner is usually poised, prim and proper, but she completely let her hair down in a recent Instagram video… and it’s gas!

The 13 Going On 30 actress only set up her account a couple of weeks ago, but she’s proving to be comedic gold. She captioned the video, “Throwback Thursday – that time I had dental anaesthesia… laughing gas + novocaine + Hamilton = you’re welcome,” and she can be seen crying and laughing hysterically in her car.

The ‘Hamilton’ she’s referring to is a musical on Broadway, about the life of American Founding Father Alexander Hamilton – and she’s clearly very passionate about it. Slurring her words through a numbed mouth, she says, “They did the sad part of Hamilton and I started crying, I couldn’t stop! And they said ‘Are you okay?’ And I said, ‘It’s so beautiful, it’s so beautiful! I listened to the song, it was so beautiful – that musical’s so pretty!”
