NY- A foot-licking sicko pleaded guilty yesterday to preying on the feet of unsuspecting female straphangers.

Joseph Weir was sentenced to four months in jail for kissing and licking the shoes and feet of women on the subway. He also was ordered to undergo counseling and was placed on 10 years’ probation for his bizarre slobbering attacks.

Weir, who bowed down and chanted, “I’m not worthy! I’m not worthy!” while trying to kiss the feet of one of his victims, pleaded guilty in Manhattan Criminal Court to sex abuse and unlawful imprisonment charges.

He previously had worked out a deal with Queens prosecutors in which he pleaded guilty to forcible touching, and was ordered to spend 60 days behind bars for offenses in that borough.

The Brooklyn man was snagged by police last May after a woman fought off his foot-licking on a Queens-bound E train. He later confessed to police that he had assaulted more than 70 women.
