Just keep him off ER...they are short staffed (wink) and every story line has blood on everyone/everywhere...never knowing if there will be car crashes, drownings, eletrocutions, planes crashes, drive by shootings, posioned food, starvation, unsafe sex, hostage situations any and all combinations before the first commercial.
OMC is much tooooooo booootiful to wear and be exposed to all that even in a cameo appearance...
