You're a failed abortion whose birth certificate is an apology from the condom factory.
You must have been born on a highway, because that's where most accidents happen.
You're so ugly Hello Kitty said goodbye to you.
You are so ugly that when your mama dropped you off at school she got a fine for littering.
It looks like your face caught on fire and someone tried to put it out with a fork.
Your family tree is a cactus, because everybody on it is a prick.
Do you have to leave so soon? I was just about to poison the tea.
Your so ugly when you popped out the doctor said aww what a treasure and your mom said yeah lets bury it
Dumb ass.
Having no life is better than having your life.
You are so annoying that people go to jail to get away from you.
We all sprang from apes, but you didn't spring far enough.
I hear when you were a child your mother wanted to hire somebody to take care of you, but the mafia wanted too much.
Out of 100,000 sperm, you were the fastest?
I would ask how old you are, but I know you can't count that high.
If you really want to know about mistakes, you should ask your parents.
I could eat a bowl of alphabet soup and crap out a smarter comeback than what you just said.
When you were born, the police arrested your dad, the doctor slapped your mom, animal control euthanized your brother, and A&E made a documentary that saved your life.
