Sort-of memes that are cracking you up at the moment

We spent days convincing a guy in our class that boys had periods too and that he was the only one that hadn't had one.

The punchline was when he came into the class a week later and proudly announced he'd had his first period, which wasn't forgotten for the remaining 5 years of high school, if indeed, it doesn't still persist to this day.
