Dangerfield, who fell into a coma after undergoing heart surgery, died at 1:20 p.m., said publicist Kevin Sasaki. Dangerfield had a heart valve replaced Aug. 25 at the University of California, Los Angeles, Medical Center.

Sasaki said in a statement that Dangerfield suffered a small stroke after the operation and developed infectious and abdominal complications. But in the past week he had emerged from the coma, the publicist said. Clad in a black suit, red tie and white shirt with collar that seemed too tight, Dangerfield convulsed audiences with lines such as: "When I was born, I was so ugly that the doctor slapped my mother," "When I started in show business, I played one club that was so far out my act was reviewed in Field and Stream," and "Every time I get in an elevator, the operator says the same thing to me: `Basement?'"

In a 1986 interview, he explained the origin of his "respect" trademark:

"I had this joke: `I played hide and seek; they wouldn't even look for me.' To make it work better, you look for something to put in front of it: I was so poor, I was so dumb, so this, so that. I thought, `Now what fits that joke?' Well, `No one liked me' was all right. But then I thought, a more profound thing would be, `I get no respect.'"

Dangerfield is survived by his wife, Joan, and two children from a previous marriage.
