Sweet moonshine

The story:

At first I was embarrassed because my mom and I were in the car together and I was singing, and she turned the radio down. She said, "What the hell are you singing?" I said, "Sweet moonshine. Why?" and she started to crack up. She was in tears by the time we got home, and when she went to tell my father about it, she couldn't stop laughing. It was babbling that was coming out of her mouth. She had to get a drink and it ended up out her nose! Now I joke around with her about it.
