I'd give him the mic and let him do his thing. Then take him in the control room and listen to the play back. Point out to him the issues with the vocal and how his mic position is creating the issue and suggest ways he may get around it - avoiding to much proximity, ducking his chin to avoid plosives, etc. Give him the opportunity to learn and improve. If he's still clueless, fvck it, it is what it is.
