A simple one line-joke that keeps on giving.
You can be talking about something completely innocuous, and a strategically inserted "That's what she said" makes it hilarious. Yes, I am very mature. I still chuckle every time Michael Scott says it on The Office. It never gets old.
Although I appreciate a good one, I don't pay enough attention or my mind just isn't dirty enough to remember to say the damn line at just the right moment. But I have to say Huz is really good at it. (And so is his cuz.) He never misses a chance when I say, "it's hard." Yeah, that's a giveaway. But sometimes he gets some good ones.
Like recently one was beyond epic!
While I was away on vacation, my mother-in-law came over to give Huz food. She made this cold beef dish for him. When I came back, Huz kept trying to get me to eat it. For a couple days at every meal time, he would insist I eat some. Finally, I yelled, "Why are you shoving that meat down my throat?!?"
The next second, I heard "That's what she said!" Then I saw Huz with the biggest smile on his face. That bastard was so proud of himself. But I had to give it to him. I couldn't stop laughing. Haha! That was awesome!
