Bell's palsy
When Barr was three years old, she got Bell's palsy on the left side of her face. Barr said, "[so] my mother called in a rabbi to pray for me, but nothing happened. Then my mother got a Mormon preacher, he prayed, and I was miraculously cured". Years later, Barr learned that Bell's palsy was usually temporary and that the Mormon elder came "exactly at the right time".
