Last month, Saul Alvarez was arrested for allegedly trying to rape a jogger in Central Park. Yesterday, he appeared in court, where prosecutors revealed he told cops after his arrest that he thought it was a hilarious joke: "When I first took her down, I said 'prank.' I've never done this prank in my life. This is the first time ever" and "her eyes made me think that she had a good sense of humor and she was a good person to play the prank on."

Cops say that Alvarez, 21, allegedly grabbed a 29-year-old woman running on East Drive near East 106th Street at around 10:45 p.m. June 29, and then put his hand on her mouth and tried to drag her into a wooded area. The victim managed to free herself and a passer-by called 911 after hearing her screams.

However, court papers note that Alvarez also said, "The only other time that I ever played this prank was on my wife few years ago and that's how we met," and revealed other "jokes" he played on people were switching out skateboard wheels with marshmallows and switching coffee with water.

Alvarez has pleaded not guilty. He faces up to 15 years in prison if convicted.
