A common suggestion/I need some help

Me: "I'm bored." Suggestion-provider: "You should write a book!"

I agree, and am going to need some book-worthy topic suggestions in the comments section of this post, please. Let's make this a joint effort. I'll keep you guys up to date on my progress! Now, remember: 1) I'm not good at writing fiction. I like real-life. Humorous subjects, preferably. 2) History isn't my greatest subject, so nothing about past wars and whatnot, ok? Don't overestimate my skills. I get facts wrong all the time.
