Eminem is back in the rap game with Tuesday's release of The Marshall Mathers LP 2, but there's one game he never left: the being-a-huge-nerd game. The rapper has long been a fan of geeky pursuits, from starring (and co-writing) his own Punisher comic book with XXL magazine and Marvel, to dressing up as Robin in the "Real Slim Shady" video. And his new album continues the trend, with a wealth of geek-friendly references that show Eminem wouldn't be out of place at your local comic store.

Em's latest album has received a lot of backlash for what some consider to be homophobic and misogynistic lyrics — backlash he addressed head-on in an interview with MTV News following a townhall-style radio interview on Tuesday — but the references below probably won't get critics too riled up.

For those Eminem fans not as geek friendly, here's a rundown of every nerdy reference on the album:

"Rhyme or Reason"

» "Back with the Yoda of rap in a spasm"
Little green creature from the "Star Wars" movies who lives on the planet Dagobah, and trains Luke Skywalker in the ways of The Force.
