This is where Sheldon gets it totally incorrect. Baseball was invented in South of England back in mid around 1740s.. by the mid-18th century a game had appeared in the south of England which involved striking a pitched ball and then running a circuit of bases. Rounders is referenced in 1744 in the children's book A Little Pretty Pocket-Book where it was called Base-Ball] English colonists took this game to North America with their other pastimes, and in the early 1800s variants were being played on both sides of the ocean. Surprised they got this incorrect.
