Dad: "Son, does mommy like having lady-friends over?"
Son: "Nah, mostly men."
Dad: "Do you think you'd be comfortable telling that to a judge in court?"
Mom's Friends
Explanation
The humor comes from the son's unexpected answer, implying the mother has male friends, not female friends, and the dad's follow up showing the awkward implications.
