How to stop seeing everything everybody likes on facebook?

Is there any way I can set my account or something so that I don't see every post, picture, page that my friends "like"? It's really irritating when half my news feed is just "John liked a post" and it shows the WHOLE thing that he liked. Is there a way to turn this off? I don't want to unfriend them or anything, I just don't want my whole page filled with stuff people liked.

Answer: 
add those people to your acquaintances list, or unsubscribe from them (you can still be friends with them)
