You shall not ass!
There's been no shortage of 50 Shades of Grey parodies recently, but this one took us all by surprise. Maybe it's because you have to know The Lord of the Rings pretty well to be aware that he's called Gandalf the Grey, but we didn't see it coming.
Which is surprising, because Ian McKellen's dialogue works surprisingly well as a creepy seductive wizard who's into BDSM. You almost wonder if that's how J.R.R. Tolkien envisioned the character. He had to be a pervert, why else would he name a character "Bilbo?"
