Is it Super-Hero Week in NYC or What?!

Julio Gonzalez, 43, and Pedro Nevarez, 40, saw 3-year-old Timothy Addo dangling from a Bronx building on Thursday, police said. The boy had crawled out of a window when his baby sitter briefly took her eyes off of him, police said.

"He was hanging on for dear life," Gonzalez said.

Hearing people in the building scream for help as the boy's grip weakened, the men rushed over to position themselves under the fire escape to catch him. (Watch man describe his life-saving catch)

"No one came," Nevarez said. "We knew it was up to us."
