King of the Nerds contestant Celeste Anderson dropped by Conan last night. The trash-talking gaming champ show her skills on solving a Rubik’s Cube in a flash. She brings along her own custom made cube and lubes it herself. Watch her solve it in less than 30 seconds.

She might seem sweet, but when Celeste gets in the zone, she lets the expletives fly.

She challenges CONAN’s own Aaron Bleyaert to a speed match and the results aren’t pretty.
