How to send a whole conversation on an iPhone?

I've recently been wanting to forward a big chunk of a text conversation, but I can't find an effective way to do it. Is there any other way than clicking edit and scrolling though and selecting each one individually?

IPhone Tip: You can snapshot part of the conversation by holding on the home button and press the home button once until the white screen flashes then check your photos to see your snapshot of your conversation. Taking snapshot works well in app games, facebook feeds, safari, and anything you can think of.
