Warring States Puns

The were The Ruff Riders.

My pregnant wife is wearing a white shirt that has a pumpkin painted over her belly, for Halloween. We are having another little girl, and have set on the name Ellie.

My daughter comes home, and is greeted by my wife.

4yo: "I like your shirt mama!

Wife: "Aww thank you! Do you like my pumpkin belly?

4yo: "...I like your pumpkin Ellie!"

Me: so what brought you to the states?

Him: An airplane.

In a perpetual state of war.

Please mention any I missed!

This was from high school before I became a dad, but I think it still qualifies.

My history teacher was lecturing on the Paris Conference following World War I. Specifically, he was discussing each of the world leaders in attendance and each of their aims for the treaty that would result from the conference.

He was going down the line of leaders and asking the class what each leader wanted in the treaty. For example, "Britain was represented by Prime Minister David Lloyd George. What did Mr. George want in the treaty?"

He got through Britain, France, and Italy, then he came to the United States, represented by President Woodrow Wilson.

He asked, "What did Mr. Wilson want?" I responded, "Dennis out of his life once and for all?"

He and I were the only people who laughed.
