Confused husband joke

Funny joke: Husband, how many days will you come back from business trip?

"Husband, how many days have you been on a business trip?" Husband calmly said, "I'm busy here, it's estimated that it will be next week." I said with shame, "honey, I'm sorry." Can you come back right away? I have been locked in the basement for two days. " The husband said, "Do you feel weak and your legs are weak?" I said weakly, "Yes." As soon as the phone hung up, I heard the basement door open.
