My roommate needs my help all the time?

anytime my roommate uses his computer he needs help. Most of the time it is stuff like, where is criagslist, or how do i find an episode of whatever. It's so annoying cause i can find all this stuff in seconds and i want to just yell at him look it up yourself you big moron. He's totally computer illiterate he doesn't know how to do anything, except ask me ******* questions. So what would you suggest i do before i explode on him?
