OMG! He did get Heinz Guderian (but he asked wierd questions - first he asked "did that person take part in WWII?" and some questions later: "Does your person play in a all-female band?"

) but he couldn't guess Freddie Mercury! Maybe the fact that I said NO to the question "Is he homosexual" (he was bisexual, I consider it a different orientation) had something to do with it...
