Robin: When I was a kid, I had this dog, Sir Scratchewan. Anyway, Sir Scratchewan got really old, so my parents decided to put him down. It was the toughest day of my young life.
[flashback to a young Robin with her dog:]
Robin: Good-bye, Sir Scratchewan, I love you.
[back:]
Robin: And when they took him to the vet, he told them that earlier that very day, he had learned about an experimental procedure called a canine/testudine cerebro-xenograft. Ever heard of it?
Marshall: No.
Robin: Well, it saved Sir Scratchewan's life. He lived another seven years.
Marshall: Miracle.
Robin: Except for one... kind of big side effect from the surgery.
[flashback to Lily with a turtle:]
Robin: Sir Scratchewan! Welcome home!
[present:]
Robin: He turned into a turtle. I know. It's weird, right? Apparently, a very common complication from canine/testudine cerebro-xenografts. And he didn't seem to remember any of his old tricks.
[flashback:]
Robin: Go get it, Scratchy. Go get it! Go get it! Get it! Go get it, Scratchy. Go get it.
[present:]
Lily: How long was it before...?
Robin: Longer than I'm proud of, Lily. Longer than I'm proud of. And that's when I realized miracles ain't real.
