Doesn’t know baby shit from butterscotch 
Doesn't have a leg to stand on 
doesn't have enough sense to come in out of the rain 
Doesn't have two nickels to rub together 
Doesn't know his arse from his elbow 
Doesn't know his elbow from a hairpin turn 
doesn't know if she's washing or hanging out 
doesn't know jack-shit 
Doesn't know shit from paint
