右邊漫畫框：... He said two jerks means 'more slack' and three means 'come up' ... (1)
The Massachusetts Daily Collegian
September 6, 1989, page 26(*2)
... He said two jerks meant 'more slack' and three meant 'come up' ... (2)
The Complete Far Side
Volume One, 1980-1984, by Gary Larson, 2003, page 260
... He said two jerks means 'more slack' and three meant 'come up' ... (3)這個上色的版本也是網路上流傳最廣的版本。我的猜測是要嘛是 OCR 掃描辨認失誤，要嘛就是單純的人為錯誤。
