It's a great quote. But the quoter and the story have no status and hence it falls flat. For example, imagine if:
1. "I'll be back" had been spoken by Jerry Seinfeld as he lamented not wanting to look like a pirate.
2. "I'll make him an offer he can't refuse" had been spoken by Meg Ryan in Sleepless in Seattle or You've Got Mail.
3. "Frankly my dear, I don't give a damn" had been spoken by Jack Nicholson in Good as It Gets.
The impact of the quote is directly proportional to the story that supports it.
