I heard someone caution young women who are about to wed with this old saying: “Remember, when you marry your Prince, you inherit the king, the queen, and the whole court!”
That warning applies to every prince marrying his princess as well. And let me add – you may also get a “court jester” thrown in as well!
Jokes about the “meddling mother-in-law” and the “grumpy father-in-law” are funny because they’re true often enough that stereotypes develop.
