After seeing you sing, the dog got disinfected from rabies.
You call me a prostitute's son, I call you test-tube babies.
Alright listen up buttercup. This dude says someone's singing is so bad it cures rabies. Then he calls them a test-tube baby in return for being called a prostitute's son. It's like, a really dumb insult battle. And you're listening to it. That says a lot about you, doesn't it?
