Ol' Fred was in the hospital, badly ill. The family called his personal physician and best friend to stand with them. As his best friend stood next to the bed, Ol' Fred's condition appeared to deteriorate and he motioned frantically for something to write on.
His friend lovingly handed him a pen and a piece of paper, and Ol' Fred used his last bit of energy to scribble a note, then immediately after, died. The friend, in his grief, put the note in his wallet and forgot about it.
2 days later, at the funeral, as he was finishing a speech about the life of his best friend Fred, he realised that he still had the note.
He said, "You know, Ol' Fred handed me a note just before he died. I haven't looked at it, but knowing Fred, I'm sure there's a word of inspiration there for us all."
He opened the note and read, "You're standing on my oxygen tube!"
