"Killah Hills" might have my favorite line: "...even underwent surgery / they said his pirate limp gave him away / as the Feds rushed 'em comin' through US Customs"
or.. "He set bombs in bottles of champagne / so when niggas popped the corks, niggas lost half their brains"
OR.. "cemetery's packed / of niggas who think 'it ain't like that'" makes me laugh
if you want to talk about best GZA verse, I'd have to exclude all of Liquid Swords and look only at guest appearances. "Silverbacks" is an incredible verse.
