Halloween is this Friday, and we’re super excited to see the nonsense sluttilicious costumes that will be spilling out of nightclubs this weekend (we’ll be sharing our favorite Halloween booties later this week – just you wait). However, before we explore the sexy, let’s check out the awkward and unattractive Jim Carrey rockin’ a pretty legit Sia costume on this weekend’s SNL. He and hilarious castmember Kate McKinnon had a Chandelier dance contest (with an appearance from Iggy Izalea and Lorne Wilson), and it was just as bizarre as you might imagine.
