Bruce Willis' speech from 2018 resurfaces after dementia diagnosis: 'Nothing can keep me down'

Bruce Willis' closing speech from his 2018 Comedy Central Roast has resurfaced and gone viral in the wake of his recent dementia diagnosis.

"Nothing can keep me down," he began in the resurfaced video. "I’ve been attacked by terrorists, asteroids, film critics, music critics, restaurant critics, divorce lawyers, male pattern baldness and none of it, none of it stopped me because I am still Bruce f--king Willis."

The moment earned cheers from the audience and roasters, which included co-stars Joseph Gordon-Levitt and Cybill Shepherd, as well as ex-wife Demi Moore. A post shared by Demi Moore (@demimoore)
