Replying to Any way of removing videos/pictures/comments?

I actively posted on this site between around 2004-2006ish when I was a teen and made some pretty immature comments and have some less than professional speech in some of my videos that turn up when I Google my first and last name. Yes, I know, I should have thought about this when I made those comments when I was like 15.

However, since we forgive and forget, I was wondering if there was some way of removing videos from your profile and deleting comments. I poked around for such a feature and unless I missed something obvious, I can't find a way. Thanks for all your help!
