Uggggggh! Prison was so dirty and disgusting, certainly not a place for a special person like Yosef.
Yet, once again, HaShem was so kind to Yosef. HaShem turned everything he did into a great success! The prison guard also began noticing that Yosef was unlike the other prisoners. He was wise and trustworthy, and always gave good advice. So little by little, the guard decided to put Yosef in charge of the other prisoners and gave him special privileges.
