Your worst call ever?

[Bad Zebra]

During my first year of varsity ball (probably 10-11 years ago), I called a back court violation on a team...problem was, I used a volleyball line instead of the mid-court line for the violation. One of my partners quickly rushed over after my whistle and told me it was the wrong line...red faced...I report: "Inadvertent whistle..play on!"

He still reminds me to this day whenever we work together.
