She holds the pen
That spills the ink

The story:

My friend and me are both fans of Metallica, and "Sweet Amber" is one of our favourite songs. One day in school, she was writing something down with an (apparently broken) fountain pen, when suddenly her hand and paper were full of ink.
"Just like in the song", I said.
"What song?"
" 'Sweet Amber' "
"WTF?"
I started singing. "She holds the pen that spills the ink..."

When she finished laughing, she told me I'd totally saved her day xD
