I'm really starting to love the Kardashian sisters. At first their sex tapes and DUIs are kind of off-putting, but the fact that they're able to joke openly with their mom about her vibrator, and demonstrate how to use a tampon and a pad to their little sisters โ€” like they did on last night's episode of Keeping Up With The Kardashians โ€” is, frankly, endlessly endearing.
