Sister jokes

So, I accidentally just tipped over my paralyzed sister.

The daughter walks up to her father and asks him, "Dad, can I ask you something?"

The father says, "Of course, what's your question?"

The daughter replies and asks, "How do you feel about abortion?"

The father says, "Why don't you ask your sister?"

The daughter replies, "I don't have a sis-"

Kid 1: "Hey, I bet you're still a virgin."

Kid 2: "Yeah, I was a virgin until last night."

Kid 1: "As if."

Kid 2: "Yeah, just ask your sister."

Kid 1: "I don't have a sister."

Kid 2: "You will in about nine months."

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***!"

You know, that I see my sister at home from school. She says everyone bullies me. I say, "Because you're a fat a**."

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

Teacher: Why did you throw paper airplanes at the twin sisters?

Me: You wouldn't get it.

Your sister is so short, she needs to roll up her panties.

As a son, I am so worried about the phone call message that my mom got from a member of The CDC. It was on speaker, so me and mom both hear. The message told my mom that she needs to personally isolate because two of the new symptoms is having big titties and a great personality.

My wife cheated on me with my brother.

She didn't have a sister, so I improvised, and now all I have to do is wait nine months for one to come.

My little sister that is 10 is so ugly her hairline can't even be found by Dora the Explorer.

Sister, you're ugly.

Other sister: I'm not your reflection.

PS. Sorry if it is not funny.

I got a pen for my baby sister. Best trade I made so far.

For dinner, this girl had noodles. The next day, she could not find her skinny sister. The mom said, "Your sister is dead!" sadly. The girl asked, "She was skinny, right?" The mom said yes. The sister laughed, "I ate her! That’s why the noodles were very skinny!"

Dentist: Open up, sir.

Me: So... I hate my life, my family, my sisters, my dog, my cat, and I tried to take a bath with my toaster, but my dog took it. That's why I hate my dog. And my cat died trying to chew my rope; it choked... Yea.

Dentist: I... meant your mouth... so I can clean your teeth.

Me: :O Ohhhh, my bad.

Dentist: Do you need help??

Me: Yep.

Dentist: ...

Me: ....

My mom said my sister was an angel, but when I threw her out the window, she didn't fly.

Your sister is your mother.

Your father is your brother.

You all shag one another.

The Inbred family.

Why was six so scared of seven? Because seven ate nine.

My mum said take out the trash, so I took my sister.

My sister: You were born ugly.

Me: I'm not a mirror, sis.
