What in your opinion is the greatest rhyme ever said in a battle?

Obviously someone like Bender has many many candidates (stargazing/carl sagan, oppenheimer/atomic bomb designer, fucked up head problems/hunter s thompson, vladimir lennin/glass at the kremlin etc etc.)

I think I remember Illmac said his favorite is HIV test/ A I D S

For me personally, it might be Ncredible vs Esem. Acting high class/Plastic wine glass

In terms of songs, Eminem rhymed public housing system/munchausen syndrome and Lupe Fiasco rhymed
fibonacci sequence/Liberace sequins, which might be my favorites outside of battle rap

But I know some of you guys are holding to gems, what you got?
