Help please, I need help liking a certain post on facebook

Hi all,

I have posted a comment on a popular facebook page with a youtube video i want to be seen.
I need to give my post upvotes (likes) so it appear on top of all the comments.

Whats the best (FREE) way to get this done?

Thanks for the help in advance!

any service that does what is mentioned above?

I think the best way is to have "your friends" on facebook share the post... otherwise you may have to "sponsor" it.
