In these trying times, it feels like the world could use a lot more humor. And Twitter users have stepped up to the plate with a new meme format that's designed to relay excellent jokes in a pretty meta manner.

A prime example is from @KaushikLab who tweeted, "I have a microbiology joke, but not sure if it is 'cultured'" We've put together some of our favorite examples, but if you're on Twitter at all you're bound to find loads more dad-approved material on the site.
