Twilight narrowed her eyes at the doorknob. Something about it felt off. Was it the roundness? It was definitely the roundness. She'd never seen such an absurdly round doorknob before! Sure, she'd seen ones that were ovals, and even some that were a little more circular than most, but one that was round enough to be reflective?
"Hey Rarity, come over here," she called, "When did you install this new doorknob?"
"New doorknob?" Rarity cantered over, joining Twilight in inspecting the doorknob. "I don't believe I ever installed a new one in the first place! Are you delusional, darling?"
Twilight shook her head. "No no no, I'm not delusional, Rarity, I'm just..." she pointed a hoof at the doorknob. "Are you aware that your doorknob's surface is so perfectly round that it has become a mirror into a parallel universe?"
"Like that mirror portal you disappear into on occasion?"
Twilight nodded, lighting her horn and pulling a

By Celestia's flaming mane, that's a lot of parallel universes where she pulled other things from the doorknob!
"But that's not the weird part."
Rarity cocked her head. "It isn't?"
"IT'S SO ROOOOOOUUUUUNNNNND!"
