Question: We're treading down a wrong path here, there needs to be some quality control in terms of answers. Just treating everything as "it's creative, don't hate" is such a bad way to regulate question and answer quality.

For example, this question: <https://puzzling.stackexchange.com/questions/3911/a-man-pushes-his-car>

An answer like this: <https://puzzling.stackexchange.com/a/3925/4425> reads just like a Y! Answer. Completely random, made up. Sure it's a lateral thinking puzzle, but that's just a bad excuse for "anything goes in this question". 

Is this just me?

Answer: 
I blame the questions.

If “solve this riddle” is a valid question, then those are decent answers.

[These puzzles are officially off-topic](https://puzzling.meta.stackexchange.com/questions/1254/why-are-questions-off-topic-if-they-invite-answers-which-are-not-demonstrably-co), but pretty much nobody appears to be enforcing this.
That is actually a good answer by StackExchange standards. The answerer provided a link to a reputable source (Wikipedia) as well as summarizing the condition in his own words. Then he explained how it answered the question.

There's some debate here as to whether we want to include well-known puzzles like these that are easily found on the web. That answer is a great reason for why we should. Most people may know (or can easily find) the classic answer, but that doesn't mean that new answers can't be discovered. Finding new answers to classic puzzles is a great way of adding value to the site and also growing and improving the art of puzzle solving.
