A man heckling First Lady Laura Bush and daughter Jenna outside the 92nd Street Y was arrested after he punched a wheelchair-bound girl whose parents had told him to shut up, authorities said Wednesday.

German Talis, 22, was shouting obscenities at the Bushes, who were leaving the building Tuesday, when he crossed paths with Wendy and John Lovetro and their daughter Maureen, 18, who has cerebral palsy.

They had been in the audience to hear the Bushes talk about their children's book, "Read All About It."

"He began yelling about Iraq and Iran at Jenna Bush. She was waving at the crowd. I told the guy, 'What are you doing? Shut up. This is about a child and books,' " said John Lovetro. "He was unperturbed. I said, 'Get out of here! You're being a moron!' "

The next thing he knew, Talis was allegedly punching Maureen, a fan of the first lady since meeting her in 2004.
