This week the No Brains, No Lightbulbs team invites Trivia Mafia writer, editor and host Megan Olson in to demonstrate her absurd real-names-of-celebrities knowledge and her even absurder love of the '90s band Jellyfish. Chuck cashes in some questions on world currencies (03:48 ). Sean and Megan get Hamburgled (18:33 ) and Megan demonstrates her superior knowledge of the real names of famous people (22:08 ). And to close, Chuck knocks it out of the park in a round called Hometown Derby (32:58 ).
