IMPUTE NAME SWEETIE BOT IS SUPERIOR PONY
From Friendship is Witchcraft, mostly the episode "Neigh Soul Sister" [link]
While I hate to say I don't find the series all that funny as a whole, that episode made me laugh my ass off, and it was mostly from little sweetie bot (she made me laugh at the end of the last ep too)
if you check out my tumblr (on which I've started posting slash that DA wouldn't be too happy with if want to see that) you'll see I've started a Sweetie bot custom pony, when she's done I'll post her here.
I wish i could send hugging sweetie bots out to all my watchers *^*
