Unattractiveness jokes
I was such an ugly kid. When I played in the sandbox, the cat kept covering me up.
Yo mama is so ugly, if she got a pound for every boy that found her unattractive, boys would find her attractive.
I bet when your mom first saw you, she said, "Oh my god, this ain't my child. My child would look amazing."
If I had a dollar for every girl that found me unattractive, they would eventually find me attractive.
