John McCain comes out:

"Dare I say Abba?" he replied. "Everybody says, 'Ugh. Abba.' Why is that? Abba was the largest-selling record act ever. Nobody likes them, but they sold more records than anybody in the history of the world, including the Beatles. But everybody hates them. You're a no-class guy if you like Abba. Why does everybody go see Mamma Mia!? Hypocrisy! Rank hypocrisy! I'm not embarrassed to say I like Abba."
