It's been mentioned several times there there's a lot of references in the FiM series that are aimed to times gone by. Be it musical influences, jokes, etc. I'm curious how many of these could be pointed out and where are they? For example:
Friendship is Magic Part 2 @ 7:45 in, Pinky Pie's song. Twighlight's reaction is because of the groaner songs in earlier cartoons
Ticket Master @ 17:30 and Bird in the Hoof @ 16:10 Benny Hill style chase scenes
I know I've seen many others, but can't think of where they were off hoof.
