Punjabi joke translated to the best of my abilities.

There’s a guy that lives in a village that is rich but illiterate. So, one day his friend whose well educated visits him and in conversation tells him that he should get an education. The guy’s like why? The friend replies:”It makes you wise.” The guy says:”How?” The friends asks him:”Well do you have a dog?” The guy replies:”yes, I do” The friend says:”That means you also have sheep. You’re father was well adjusted and well respected man of the community. You’re mother was a respected women with great reputation.” The guy is just baffled about how this is all true but at the same time is like I understand how this works. The next day his servant is serving him some tea. He tells the servant:”Hey Sharfu. You should get an education” The servant is like:”Why,Master?” The guy:” Education makes you wise.” The servant just doesn’t understand and the guy asks him:”Do you have a dog?” The servant replies:”No, Master.” The guy after thinking for a while says:”Don’t come to work from tomorrow.” The servant asks why? The guy says”:It’s because you’re mother had a promiscuous reputation.”
