Ol' Fred had been a union man and was in the hospital, near death. The family called the union boss to stand with them. As the union boss stood next to the bed, Ol' Fred's condition appeared to deteriorate and he motioned frantically for something to write on.
The union boss handed him a pen and a piece of paper, and Ol' Fred used his last bit of energy to scribble a note, then he died. The union boss thought it best not to look at the note at that time, so he placed it in his jacket pocket.
At the funeral, as he was finishing the eulogy, he realized that he was wearing the same jacket that he was wearing when Ol' Fred died.
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 out loud, "You're standing on my oxygen tube!"
