Sister jokes

One time I looked out the window and then I saw my sister, and she wasn’t even my sister anymore...

I see my friends at school. They talk to me, they go back to class, but they forgot I am their classmate, and they were like, "You're a dumbie." And I was, "Well, you're a dumbass, bi***!"

I told my sister that when you go to bed with an itchy butt, you're going to have smelly fingers in the morning, and I've never heard her laugh so hard in my life.

My sister lost two things today:

1: Her virginity.

Sometimes I feel ugly, but then I think of my sister.
