Kid Show?

I was flipping through channels last night, just killing time waiting for a commercial break to end on another, and I happened upon the old X-Men cartoon. And in the minute I was watching, I was surprised when Beast is talking to Cyclops about who-knows-what and he quotes Emily Dickinson. I guess it just seemed strange to me that this show, which I had always assumed was targeted at a group of kids who wouldn't know who Dickinson was at all, would be quoting her.

For reference, the quote was something like "Parting is all we know of heaven and all we need to know of hell." I can only assume that it had something to do with Jean Grey/Phoenix/whoever, if memory serves.
