humor is too broad. If you give me some more info I can give you ideas. I write articles and have written over 700 on one topic so I can safely say I can generate ideas.

Humor is pretty broad, and getting more specific can help generate ideas. Are you more into political humor, humor for kids, adult humor, physical humor, comics, stand-up humor? If you're really burned out, you can outsource the idea creation to a writing company and simply ask the writers for 10 blog titles on your type of humor.

I try my best.

Also thanks for the practical joke idea. I got a nice post out of that; this guy was pouring shampoo on this kid who kept trying to wash it off. The kid had no idea about the guy and started getting really upset because he just couldn't get the shampoo to wash out. It was awesome. Link to it: The Shampoo Prank

There are gazillions of pages out there that deal with all sorts of humor...
on fb / Pinterest you can even see what gets shared and what people enjoy.

...go out and dig for inspiration.

Your topics could be " Deal with the ghost"!!!

just make them laugh

Maybe for a while you can include a collection of funny pictures. Like one post about funny dog pictures, then funny cat pictures (just an example). Or one post about a collection of funny quotations about the workplace, school, etc. I do this collection stuff when I have nothing to write but need to post something on my blog.

Let me just share a few sites that I've always found entertaining and humorous. Try cracked.com, buzzfeed and 9gag. Cracked has more interesting articles that are both informational and funny; Buzzfeed is also similar and 9gag is similar to tumblr where you can post memes or some other funny pictures you've created.

I hope you get some fresh ideas there!

Never heard of 9gag, but it looks awesome! Thanks very much.
