The TODAY meteorologist and co-host took issue Monday with comments Maher delivered on his HBO show last week in which he said fat-shaming "needs to make a comeback" and that "some amount of shame is good."
"As somebody who has struggled with his weight all of my adult life and my childhood, and who had been bullied and fat-shamed if you will, even though we didn't have that term then, it scars people,'' Al said on the 3rd hour of TODAY.
"Let's be honest, fat-shaming is just bullying,'' he said. "It's bullying, and bullying only makes the problem worse."
Al also believes that any amount of fat-shaming is not positive.
"And guess what, we all know we're overweight,'' he said. "We all know we're fat, we all know we need to lose weight.
"Bill Maher needs to shut the front door. He doesn't know what he's talking about, and it's not gonna help anybody."
