“snarling like a chainsaw trying to sing opera”
“The earth was once molten rock and now sings operas.”
“I hope you don't snore," Otto said, laughing."Like a chainsaw, my friend, like a chainsaw," Wing replied, grinning.”
“There's no half-singing in the shower, you're either a rock star or an opera diva”
“Opera is when a guy gets stabbed in the back and, instead of bleeding, he sings.”
“No opera plot can be sensible, for people do not sing when they are feeling sensible.”
