Dr. Rodney McKay:
Let me ask you a question. Say there's a runaway train. It's hurtling out of control towards ten people standing in the middle of the tracks. The only way to save those people is to flip a switch - send the train down another set of tracks. The only problem is there is a baby in the middle of those tracks.

Teyla Emmagan:

Ronon Dex:
Or better yet, go get the baby.

Dr. Rodney McKay:
For God's sake! I was just trying to...
