There are some pranks everyone thinks happened at their school. And sure, they happened *somewhere*. But probably not at your school. Like this one, where three pigs were let loose and numbered 1, 2 and 4, so teachers spent ages looking for the other one.
Another example, okay? Look at the picture: someone did it! But if the cool guy two years older told you he saw it happen a few years ago, HE PROBABLY DIDN'T. Putting cups out takes fucking ages. Who can really be bothered? It's not even that legendary.
Ah, the old putting-fish-in-the-air-vents-so-the-whole-school-smells trick. Yep, it's been done. But have you seen it with your own eyes? If not, it was probably another school with more badass students that got the job done.
And finally, releasing LOADS of crickets onto school grounds. We heard it happened at our school, but guess what? IT FUCKING DIDN'T. But it did happen, once. Just exercise some scepticism when the graduating class tells you stories, okay? FFS.
