What is the worst lie you ever told?

I tend not to tell any lie that will hurt people, but when i was a child, i lied once to my parents,I told her my brother had broken her favourite antique which she asked us not to touch , my brother even helped me and confessed everything, but my mother was so angry. After that, i always think becuase of it, my mother tend to love me more than my brother,,althogh it may not be the truth,but i really want to take it back to see will it be the same if i am the one who confessed everything.....
