From issue #3 of Phil Foglio's 1991 Angel and the Ape mini, it's Sam vs. Gorilla Grodd in a story that not only tied in with the rest of the Gorilla DCU but also featured the Inferior Five. Phil Foglio is a frickin' genius—you are reading Girl Genius, right? Angel and the Ape may not be his best work, but the next time you're rummaging through a quarter bin, seek it out for some fun comics reading.
(Standard disclaimer about apes not really being monkeys applies.)
