Thats what she said jokes

I was at school today, and one of my friends said after a test, "Man, that was hard." After that, I started laughing and I said, "That's what she said."

I was at a funeral and told a joke, and my sister said, "I'm dead." So I said, "That's what she said."

When I went to basketball training, there was a giant bag of basketballs on the floor.

My friend was like, "That's a huge sack of balls!"

He didn't realize what was about to happen.

"That's what she said!"

"Fuck me."

That's what she said.
