Without a context, we can only generalise. So who's up for comedic suggestions on what has caused this? Mine first.

Mac on being asked if Applebloom is a good stallion manestylist after she snuck into the fermented cider before doing Mac's mane.



Edit: I realise after that this possibly has something to do with episode 10 I haven't watched yet, doesn't mean we can't have fun with it.
