Marvin was in the hospital on his death bed. The family called Marvin's preacher to be with him in his final moments. As the preacher stood by the bed, Marvin's condition seemed to deteriorate, and Marvin motioned for someone to quickly pass him a pen and paper. The preacher quickly got a pen and paper and lovingly handed it to Marvin. But, before he had a chance to read the note, Marvin died.
The preacher, feeling that now wasn't the right time to read it, put the note in his jacket pocket. It was at the funeral while speaking that the preacher suddenly remembered the note. Reaching deep into his pocket, the preacher said, "And, you know what, I just remembered that right before Marvin died, he handed me a note. Knowing Marvin well, I'm sure it was something inspiring that we can all gain from."
With that introduction, the preacher ripped out the note and opened it. The note said, "HEY, YOU ARE STANDING ON MY OXYGEN TUBE!"
