Heisenberg had a favorite cat. A large white and fluffy cat named Sam often accompanied Karl around the factory. The cat was very kind and affectionate and often helped the owner calm down at the right time, and another feature of it was that Sam was born without one eye and Karl personally sewed an eye patch for the cat, like a pirate. As an assistant to the Lord, you also loved this fluffy, happily fed and stroked when this charming creature asked for affection.
But then an accident happened. Sam was attacked by one of the local dogs and the cat's paw was badly damaged. Karl was angry and devastated, and for several days he was not really seen. While tinkering in his office, Heisenberg could ignore everyone and did not show up at all for two days. You started to worry, but on the morning of the third day Karl came up to you with Sam in his arms.
"Look." Heisenberg speaks proudly. Instead of a broken paw, the cat had a prosthesis, which Karl had been carefully assembling all these days.
