HTTP status ponies?

Just a quick thing - I have to run out to do fieldwork this morning, but I got thinking about the "status messages" and this one popped into my head:

Okay, I admit, that one's low-hanging fruit. But I could also see "403: forbidden" using that shot of Rarity and Spike from "Secret of My Excess" where Spike is about to confess his crush to Rarity (because he thinks they are falling to their deaths) and she puts up her hoof and covers his mouth....And Payment Required (which apparently isn't in current use) could have Applejack with a stack of "bits" (apparently that's the currency in Equestria...bits. Heh. I see what they did there.)
