Heh, don't have much time, so shortened geek out on what I can remember:

They couldn't have gotten a wagon rather than balance it on poor Big Macintosh's back? ^_^;  I love how everyone was involved in that.

AJ with her tongue hanging out in anticipation of how good the cake must be was too cute.  And later on, when RD was rubbing her tummy at the description of the other goods.  Oh, my gosh, the cuteness level just kept rising!  ...Of course I focus on my two favorite characters ^_^;

If Griffons are so rare, why is there a griffon who apparently lives close enough to Ponyville to board on the Ponyville train station?

And Pony Joe?  How CONVENIENT you HAD to come to Ponyville to get your ingredients.  Nice to see him back, though.  As...James Bond, apparently. Who gets all the mares....Heh, Berry Punch just threw herself at him

And I laughed so hard at the silent movie version of events, and Pinkie being tied to the Railroad tracks.  I can't even...it was just too funny!

When Twilight took over, I love how she switched that hats.  Because you can't be Sherlock Holmes without the right hat.  She even took the bubble smoke-thingy.  What are those things called again?  A smoke pipe, right?  Pinkie is rubbing off on Twilight.

"Are you okay, thief?"  That was too cute, too Pinkie, and too MLP.  I loved that part.

I knew it had to be one of the mane six, then I knew it had to be three of them when Twilight started investigating, but I honestly thought the second culprit pretending to be the conductor was going to be AJ.  She seemed the most enticed by the cake at first.  But then again, she IS the element of Honesty, and it would have been weird if she did.  You go, AJ.  Being the only one, aside from Twilight, not to get a piece of cake...poor things.

Oh, and how much longer are we making this trip to Canterlot?  It's like RIGHT THERE!!  They can see Canterlot in the distance!!  I thought it would be maybe an hour's train ride, tops, since people get there by chariot, but now it's an OVERNIGHT trip?!  I'm so confused...  What, did they go all around Equestria before going to Canterlot?  I guess the train ride is only as long as they needed it to be.  

But still, seriously, they can SEE Canterlot in the distance...The Princess rode from there on chariot herself in what was, like, seconds.

...this is gunna bug me.

I'm sure I forgot a lot of stuff, but this was a really cute episode!  Pinkie is starting to be a little more dear to me ^_^  Anyways, gotta go.  Thoughts?  Things I forgot to mention?  Like the fact that Rarity wears fake eyelashes?  How did y'all like the episode?
