An Old Man With A Lisp And His Grandson Go To A Car Dealership...

So a few years back an old man goes to a car dealership my dad works at. My dad and his boss greet the man out front and when the old man started to explain what's wrong with his car they couldn't understand a single word due to his lisp. So my father and his boss are confused and they look to the old man's grandson who then tries to translate for his grandfather, but he also had a lisp. The boss looks at my dad and my dad looks at him and says "Well he must have been home schooled"
