Dunked for a great cause!

'This Is Us' star (and Gilmore Girls alum) Milo Ventimigilia stops by the Ellen Show and gets dunked by guest host Miley Cyrus.

The dunk tank is a standard for the show, used throughout October to raise money for breast cancer awareness.

Watch 'This Is Us' Tuesday nights at 10:00 on NBC 12 and Ellen weekdays at 4:00, followed by First Coast News.
