I bought some batteries, but they weren’t included. So I had to buy them again.

Cocktail Party Physics: batteries not included
Some historians believe primitive batteries were used in Iraq and Egypt as early as 200 B.C. for electroplating and precious metal gilding. Around the 1790s, through numerous observations and experiments, Luigi Galvani, an Italian professor of anatomy, caused muscular contraction in a frog by touching its nerves with electrostatically charged metal. Later, he was able to cause muscular contraction by touching the nerve with different metals without a source of electrostatic charge. He concluded that animal tissue contained an innate vital force, which he termed “animal electricity.”
