Or they could fake insanity to get a deferral, as the brave conservative Republican Ted Nugent did:

Ted, on his draft interview:

"I got my physical notice 30 days prior to. 

Well, on that day I ceased cleansing my body. 

No more brushing my teeth, no more washing my hair, no baths, no soap, no water. 

Thirty days of debris build. 

I stopped shavin', had a little scraggly beard, really looked like a hippie. 

I had long hair, and it started gettin' kinky, matted up. 

Then two weeks before, I stopped eating any food with nutritional value. 

I just had chips, Pepsi, beer-stuff I never touched-buttered poop, little jars of Polish sausages, and I'd drink the syrup, I was this side of death.

Then a week before, I stopped going to the bathroom.

My pants got crusted up.

So I went in, and those guys in uniform couldn't believe the smell. 

I knew I had these chumps beat."



Incidentally, there is no such thing now in the US military as a "draft deferral".

There is no draft.
