Baseball anthem "Take Me Out To the Ball Game" actually has two main verses. During the 7th-inning stretch, fans traditionally sing just the refrain. Jack Norworth had never been to an actual baseball game when he wrote the song.
DID YOU KNOW? Marlon Brando hated memorizing lines so much that he posted cue cards everywhere to help him get through scenes.
He even asked for lines to be written on an actress's posterior. (That request was denied.)
