What would you do parents if your child . . . . .?

Ok I found out tonight that my 13 year old daughter watched cheech and chong ( Not sure which one ) ," Jay and Silent bob "and "harold and kumar 2" . I told her not to watch "Cheech and Chong" . She knows before she rents a movie with her friend she needs to check it with me. I am really mad about is I watched the "Harold and Kumar" movie today and it was rated PG-13 but the first 6 minutes of it the guy had come on his face. Bottom - less girls and guys and a slut house . I told he not to watch the "Cheech and chong" movie when she asked 2 weeks ago. Plus I told her not to watch movies without my permission. She does not know that I know yet.What would you do if you where me?
