Elisabeth Moss of the hit television show, Mad Men, was recently on another show called, Watch What Happens Live. The actress, who plays the reserved but ambitious character, Peggy Olson  in Mad Men, was dishing with host, Andy Cohen about Jeremy Piven, who she was co-starring with in a Broadway production of Speed the Plow, and, she talked about what has now become the famous manhood of her Mad Men co-star, Jon Hamm.  

When Moss was asked about Piven, she gave Cohen an earful.

According to Us Weekly, Cohen asked Moss about her Speed-the-Plow costar, who backed out of the Broadway production, claiming mercury poisoning. Cohen asked,  "What, besides eating too much sushi, caused Jeremy Piven to quit Speed-the-Plow?"

"That's a very good one. I could go on and on," Moss said before adding, "Being highly unprofessional."

She didn't stop there.

"We were all surprised," Moss continued. "It came out of nowhere. He just didn't come back one day."

The 30-year-old beauty also noted that she saw Piven nearly one month later at the Golden Globes, when he was supposed to be incredibly sick.

In addition to Moss, Piven received bad press from Speed-the-Plow production who sued the actor for breech of contract. Piven was later vindicated when a judge ruled in his favor, reported US.

Cohen also asked Moss about the rumors that her Mad Men costar, Jon Hamm, has "impressive anatomy." 

"Is it true what they say about Jon Hamm's ham?" he asked.

"Well, I mean, we've all seen the pictures so, I mean, I would suppose so," Moss said with a smirk. "That's all I know," reported US.
