One day, an oddly robed pony with a seriously chilled out vibe was spotted wandering around Canterlot. He kept telling ponies "A new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another."
"But, uh, we already do that," the towns ponies replied. I mean, they didn't want to crucify him or anything, but he was kind of causing a scene at one of the local markets. Celestia was called in to intervene, which is good, because she was really bored that morning.
When she spotted him, she neighed in excitement and galloped over. "Yo, pony Jesus, what's up, my dude?!"
"Celly! The second coolest horse behind Slepnir! What's crackalackalin?!"
They hugged it out. "Dude, did Tree Hugger give you some sick ganja or something? I think you're in the wrong universe."
Pony Jesus whispered into her ear. "Dudette, let me hang out with you. Heaven is boring. I need to get some kicks."
So they went and pranked noble ponies together, because noble ponies always deserve that, regardless of which universe.
