"Wifers," according to Maher, are those who question whether presumptive Republican presidential candidate Mitt Romney has more than one wife.
"The media can keep giving this [birther] story oxygen, but I think they are neglecting a much bigger scandal which is wiferism," Maher said on his HBO show, "Real Time with Bill Maher."
He continued, "Mitt Romney comes from a Mormon background, I don't know how many wives he has -- I'm not saying I believe in that, I'm just saying, he was born on a Mormon compound....Again, I'm not a wifer, I'm just saying he has the blood of a nomadic polygamist tribesman, and I think that has shaped his world view."
Showing a copy of the Romneys' marriage license, Maher said he tried to get the original but could only get a copy -- and questioned why it was only the "short-form license."
"And why, why next to Ann Romney does it say 'spouse' and not 'only spouse'?" he wondered.
Showing a picture of Romney with a "strained look on his face," Maher observed: "That's the look of a man who hasn't been able to get into the bathroom since 1988."
With another photo of Romney during the 2002 Olympics with the Olympic rings in the background, Maher asked: "What is Mitt pointing to here? Five rings, what else has five rings? Five wives."
"And why did Mitt Romney strap his dog to the roof of his car? Could it have been because the station wagon was full of wives?" Maher asked.
