After winning his task as project manager on The Celebrity Apprentice by doing a promotional video with a mop, Lou Ferrigno donates the money that he earned to a young girl living with muscular dystrophy, which causes him to well up as he reminisces upon his struggles with hearing loss as a child.

In the featured sneak peek above, Ferrigno meets with Abbey Umali, who struggles with muscular dystrophy in her legs, and her parents and shares with them how he relates to Abbey.

"Close to birth…I lost like 80 percent of my hearing and I had difficulty speaking," he recounts. "It had always been a challenge for me but as a kid when I was growing up, you never want[ed] to feel sorry for yourself, ever."

Ferrigno finds himself misty-eyed as he continues to recollect his childhood struggles. "I feel like I went back in time [to] when I was a child," he said in a later interview. "She reminded me of what I had when I was young."
