If there's one thing Harry Potter fans know, it's that Fred and George Weasley are master pranksters.
I mean, this timeline is seriously impressive. It's got everything from them bewitching snowballs and making them follow Professor Quirrell around...
...to "improving" Percy's Head Boy badge...
...to accidentally turning Neville into a canary...
...to all of their ingenious inventions.
Doesn't this just make you love (and miss) those Weasley boys even more?
