An autograph hound outside of Nobu in NYC just happened to have a copy of former President Clinton's book, and repeatedly begged the dapper ex prez to sign it as he left the fish house.
Watch the footage -- Bill finally tells one of his Secret Service dudes to grab the book -- the autograph hound says, "Is he gonna sign it?" The edgy Secret Service dude says, "No."
Listen to the ink seeker's reaction. Priceless. We're told Clinton did sign the book.
