Serialization to yaml


I m serializing an object so that I can send it by email easily. However my serailized object sometimes have a lot of quotes in it like :

"   commentable_type: BlogPage   updated_at: 2008-07-14 19:55:03   title: ""   rating_total: "-3"   id: "2"   commentable_id: "24"   rating_avg: "-3.00"   rating_count: "-3"   user_id: "8" "

How can I possibly remove these quotes.

Thanks in advance,
