Yo momma's so ugly people go as her for Halloween.

Yo momma's so ugly that when she sits in the sand on the beach, cats try to bury her.

Yo momma's so ugly she scares the roaches away.

Yo momma's so ugly I heard that your dad first met her at the pound.

Yo momma's so ugly that your father takes her to work with him so that he doesn't have to kiss her goodbye.
