Carnegie Mellon Professor Randy Pausch is best known for the words of wisdom and wit he delivered during a now famous “Last Lecture” and subsequent best-selling book.

And so it probably comes as no surprise that the final words uttered by Dr. Pausch before his death last Friday from pancreatic cancer reflected the same humor and good nature that made him an Internet celebrity.

Last night, ABC aired a tribute to Dr. Pausch, replaying a Diane Sawyer special about his life and experiences that first aired in the spring. The segment also included new interviews with his close friend Steve Seabolt, who was with Randy during his final moments and noted that his “trademark wit and intellect were intact.”

Mr. Seabolt only shared a few moments with viewers, noting that even near death, Dr. Pausch’s sense of humor remained. He said Dr. Pausch talked about how glad he was that he was home and his family and friend were close, and laughed, saying, “I just feel so bad about the dying part.”

Mr. Seabolt also relayed a conversation he had with Dr. Pausch’s 6-year-old son, Dylan. They were talking about cancer and he told the boy that “some problems can’t be solved, or they can’t be solved yet.”

Dylan responded, “My daddy has taught me that every problem can be solved, and that I should believe that every problem can be solved, and that I’m strong enough and smart enough that I should never let a problem get in my way.”

At the end, as Dr. Pausch’s body was clearly failing, Mr. Seabolt said he told his friend, “It’s important for you to feel like you can let go. It’s okay.”

Dr. Pausch’s reply: “I’ll get back to you on that.”

And those, according to Mr. Seabolt, were the final words of Randy Pausch.
