I have been called a pompous ass because I can be blunt. but then, the person followed my advice and ended up on Page One within a couple of days. And he's been there a few more times since then.

If you use any template like the above one that uses speech balloons, don't use the default font settings. the reason is it makes the meme easier to read. don't be afraid to use old jokes. half of the joke memes that make front page are old jokes with a fresh approach.

No, I didn't make it. there are many good meme makers here.

Need ideas for memes? Old joke books can be a source of those pieces of gold.
