Missing out on or not understanding a joke is not fun. Sometimes, a person misses out on critical context pertaining to the joke, making it unable to understand, or someone hears something incorrectly. Sometimes, a person doesn't understand the joke, like with inside jokes or science jokes, and others times, someone simply lets the joke fly right over their heads, even when it was so obvious.

When someone misses a joke in person, usually it can be played off and forgotten fairly easily. People don't remember things like that, usually. When someone misses a joke online, though, it's so much worse because it is on there forever and ever. There are some insanely obvious missed jokes that make a person wonder how on earth they could have missed it, are they that oblivious?

Common sense was not so common in these cases. Take a moment to see just how someone missed a very obvious joke, and see what they did about it. Don't end up being one of these people, it's just cringe.
