The “Friends” actor better known as Gunther announced his diagnosis Monday on “Today.” His condition was already advanced when found out in September 2018 during an annual checkup. He’s now paralyzed and undergoing chemotherapy. His goal now is to save at least one life by sharing his story. I thought he looked a little sick on the Friends reunion... hopefully by some miracle he can beat this. Photo: Getty Images
