Super Bowl sign language guy tells TMZ, his hands are JUST LIKE Dolly Parton's boobs ... J. Lo's butt ... or Tom Jones' chest hair -- so valuable they need their own freakin' insurance policy ... but there's a lot more to sign language than just hands.
John Maucere -- who signed "America the Beautiful" and the national anthem at the big game -- was out in L.A. yesterday with his interpreter when we asked how important it is to take care of your hands as a professional sign language-er.
John raised his hands, joking, "I have insurance."
He added, "Hands are important, but you should know American Sign Language isn't specific just for hands ... There's a lot happening on my face, with my mouth, with my body, the emotions, everything. That makes the entire language."
John also answers the ultimate question -- if he had to choose ... which finger would he chop off???
FYI -- Dolly reportedly had her breasts insured for $300,000 per boob, J. Lo $27 million for her butt, and Tom Jones $7,000,000 for his chest hair. It's not unusual.
