Then there was Pavarotti's (sp) sad clown... I don't reckon he would've been much help in a survival situation either.
Everyone has a place. You could tie Pavarotti to the hood of the truck and use him as a siren. The guy can really project with that set of pipes. Might work as a pretty good PA system also.
In the bright clown outfit I remember him in he could work a flashlight in each hand and substitute for a light bar.
