Fourth uithangbord

Everyone says Pinkie Pie is known for 'breaking the fourth wall'. But other than the last her closing line in Over the Barrell and saying 'walls closing in' when the Camera zoomed dramatically in on her in Too many pinkie pies..

Oftan those brief moments, I honestly never see the signs of Pinkie prividing fourth uithangbord humor, (witch is one of my favoriete types)..

Partially compared to characters like Peter Griffin in Family guy.. Who obviously gives awareness of being a cartoon character on a fictional program, and has jokes about it, mostly poking fun a Fox...

But is there something I'm not seeing with Pinkie's character?
