Quote "Fire, FIRE, ARRGHHH!!!"

Oog is a caveman who was educated through Frylock's second OoGhiJ MIQtxxXA (Klingon for "super galactic intelligence"). He was able to live for thousands of years, and the OoGhiJ MIQtxxXA made him super intellegent, although he still has some prehistoric traits, such as his fear of fire (Even though he loves cigarettes), his constant need to be entertained, and his urge to rip his own head off, and he doesn't seem to know how to properly tie his tie. He also wants games with 'action missiles' and loves shiny things such as keys.
