No, seriously. Snopes says so.

“When I was in my routine training for the Israeli army as a teenager, they discovered completely by chance that I was a lethal sniper. I could hit the target smack in the center further away than anyone could believe. Not just that, even though I was tiny and not even much of an athlete, I was incredibly accurate throwing hand grenades too. Even today I can load a Sten automatic rifle in a single minute, blindfolded.”
