They might not all be considered canon, but I noticed a few interesting ones.

In season two's DS, Wendy was reading about an apprentice about to cast a magic spell. Lo and behold, it was the Sorcerer's Apprentice. Nice foreshadowing if it was put in! (I still want to believe that the Darlings are from a fictional time period.)

Rumple chased Rip Van Wrinkle through the woods after being drunk and he needed more time to pay his debt, so Rumple gave him a slight means of immortality as he put him asleep for a hundred years.(3's DS)

They later mention Rip on the radio when Emma's magic (in a contrived way) went berserk.

I find them quite interesting.
