This peeper's pucker landed him in jail.

Robert Neal Smith, 41, was sentenced to five months in jail Friday after pleading guilty to peeping into his neighbor's windows. He was charged with five counts of being a Peeping Tom after his lip prints matched ones left on a window in August.Police had lifted the impression in September and obtained a search warrant for Smith's lip marks. The state crime lab claimed the two were a match.

Smith told the General District Court judge he was drinking heavily when he peeped into his neighbors' homes. At one point he was chased by a woman's husband and another woman caught him tampering with her window screen.
