Barney wears a neck brace when he meets Nora, in an attempt to gain sympathy from her. When Nora asks why he's wearing a neck brace, he tells her that he was in a performance of 'Fiddler' and there was an accident involving a Roof.
Fiddler on the Roof is a musical with music by Jerry Bock, lyrics by Sheldon Harnick, and book by Joseph Stein, set in Tsarist Russia in 1905. It is based on Tevye and his Daughters (or Tevye the Milkman) and other tales by Sholem Aleichem. The story centers on Tevye, the father of five daughters, and his attempts to maintain his family and religious traditions while outside influences encroach upon their lives. He must cope with both the strong-willed actions of his three older daughters-each one's choice of husband moves further away from the customs of her faith-and with the edict of the Tsar that evicts the Jews from their village.
