Yesterday was my first time watching Dennis The Menace since I was a kid. Did you ever pick up the adult jokes?
There’s one where Dennis explains to his neighbor, Mrs. Wilson, that his dad is mostly happy. Except on Sunday mornings when his dad and his mom “wrestle” in their bedroom:
* Dennis: [in an attempt to give Mr. Wilson his ‘I’m Sorry’ card] I’m kind of busy today, so I won’t have a chance to give it to him. I have to go to Margaret’s house, because we’re getting poor and my mom’s got a job now. So could I just leave it up by his whisker-cutter? That’s where I leave all my dad’s ‘Sorry’ cards, and it’s a good time to say you’re sorry. ‘Cause grownup guys are happy in the morning when they wake up. My dad’s so happy, he whistles when he goes to the bathroom. The only time he isn’t happy is on Sunday morning when he and my mom wrestle. They kind of like to be alone when they do that. I think it’s ’cause they take off their shirts and then they start to make funny noises.
* Mrs. Martha Wilson: [uncomfortable about what Dennis is saying] Uh, you can go up, as long as you promise not to disturb Mr. Wilson.
* Dennis: I promise.
