What does you can lead a horse to water but pencil must be mean?

This looks like a playful twist on the common proverb "You can lead a horse to water, but you can't make it drink."

Here's how the twist works:

* Original Proverb: This proverb means you can present someone with an opportunity, but you can't force them to take advantage of it.

* Twist: The twist replaces the "make it drink" part with "pencil must be mean." This suggests that a pencil is not simply an instrument for writing, but rather has some kind of agency or personality.

Possible Interpretations:

* Humor: This might be a humorous take on the proverb, poking fun at the idea that a pencil could be "mean."

* Metaphor: Perhaps the "pencil" represents something else, like a tool for learning or expression. The "meanness" could symbolize a reluctance to engage with these tools, even when they are available.

* Wordplay: It could simply be a play on words, using the similar sounds of "mean" and "means" (as in "by all means").

Without further context, it's hard to know the exact meaning of this phrase. It's likely a playful twist on the proverb, intended to be humorous or thought-provoking.
