One day this mom noticed a very strong citrus smell coming from her bathroom...

She discovered a strange blob in her potpourri bowl...

Her young daughter later walks out holding it to her nose and telling her mother how great it smells.

Mom agrees and ask where the mysterious blob came from...

She said her little brother brought it home from the bathroom at karate class...

Mom (rightfully) freaked out after realizing it's a used urinal cake.

Damn, that's just nasty!
