Sometimes metaphors are best left unspoken, a hard lesson learned by country singer Hank Williams Jr. when he compared U.S. President Barack Obama to Hitler in an interview on Fox News Monday, Time Magazine reported.

The conservative country singer, known for his "All My Rowdy Friends Are Coming Over Tonight" intro, that has been used as the opening song for ESPN’s Monday Night Football, criticized Speaker of the House John Boehner for playing golf with Obama, saying that it would be like Hitler playing golf with Prime Minister Benjamin Netanyahu, Time reported.

He then reportedly went on to say that Obama and U.S. Vice President Biden are “the enemy.”

ESPN pulled Williams’ intro from Monday Night Football due to his offensive comments, Time reported, though he is not a direct employee of the sports network.

The country singer clarified his comments shortly after the interview, Time reported, saying that he was criticizing the Obama administration because "working class people are hurting – and it doesn't seem like anybody cares. When both sides are high-fiving it on the ninth hole when everybody else is without a job – it makes a whole lot of us angry. Something has to change. The policies have to change."

In response to the comments, Abraham H. Foxman, director of the Anti-Defamation League, who is a holocaust survivor said that, “Hank Williams Jr. should know better. He owes an apology to Holocaust survivors, their families, and the brave American soldiers who gave of themselves to fight the Nazi menace during World War II."

"The last thing we need is to enter another election cycle on a sour note tainted with inappropriate, tired and over-the-top analogies to the Nazis,” Foxman added.
