Unfortunate typo

The orders of service are now printed, copied, stapled and ready to go. They’ve been spell-checked and proof-read and seem to be fine. The church administrator was telling me a story about a friend who spell-checked but didn’t proof-read the order of service for her wedding. A typo towards the end of verse 4 of the hymn “And can it be that I should gain?” had a letter “a” missing from the word “chains” resulting in the line reading “My chins fell off, my heart was free” Hopefully we won’t make any similar errors, but it is a funny story!
