According to the gossip rags it's best not to tease actor Jeremy Piven about fish. After leaving a Broadway show this year over because of alleged mercury poisoning from bad fish Piven is a bit uptight about the subject.
While Jeremy Piven may say that mercury poisoning lead to him leaving Speed the Plow others say he was fired. The star claims that he left his run early because of mercury poisoning. The word out though is he was booted off the show for being a diva.
