You saw his work in Neon Genesis Evangelion:

Comic Tribute...depicting the truth about Rei with great sensitivity...wait, that's not the right word What's the opposite of "great sensitivity"? Well, whatever it is, Tony Takezaki's got it, in this collection of all-new stories satirizing both the Evangelion you saw on TV, as well as some scenes that apparently never got aired! SEE! Eva as a 1960s TV show! SEE! Kaworu and Shinji's standup comedy career! SEE! Ritsuko's days as Gendo's student intern! SEE! Eva Units, flinging dookie! You'll see all that and more, because this is Tony Takezaki's Neon Genesis Evangelion!
