IF YOU EVER NEEDED A JOINT

On Joe's gravestone, 

these words will be etched:

"If you ever needed a joint,

you could count on Joe."

On Rey's gravestone, 

these words will be etched:

"If you ever needed a joint 

and Joe didn't have one,

you could count on Rey."

On Dave's gravestone, 

these words will be etched:

"If you ever needed a joint 

and neither Joe nor Rey had one,

you could count on Dave."
