"Morris and Sidney" joke

Morris and Sidney were discussing the prospects of their upcoming retirement. While Sidney had lots of hobbies, Morris had none and was rather concerned about having nothing to do.

Sidney suggested his friend go visit his kids. Morris said, "Well, I only have two kids, but I could buy a motor home and go visit my brothers and sisters a couple of weeks each. That would take about a year."

Sidney looked a bit puzzled, so his friend said, "I'm one of eighteen kids in my family."

Sidney's eyes got rather large, contemplating eighteen children, so Morris volunteered to explain.

"The problem was, my mother was hard of hearing."

"What do you mean?" asked Sidney.

"My Mom and Dad would go to bed at night, and my Dad would ask,' Do you want to go to sleep, or what?' and my Mom would say,' What?'"
