when you laugh like a maniac and start singing like you're in a really bad band

At the dinner table, my brother got Ladonna syndrome and sang ‘Livin’ on a Prayer’ to my sister’s soup.

During my science class, I started laughing and sang ‘Don’t Stop Believin’ to my teacher.

At the bus stop, I saw a guy laugh and sing ‘Sweet Caroline’ to a pigeon.
