In Star Wars, a single clone has more brain cells than all Jedi combined.
Correct, but to expand; Marshal Commander Cody has more brain cells than all the Jedi combined, and that’s still less than 17.
Meanwhile, Anakin Skywalker has -12 brain cells, and no one’s sure how that’s possible, but they’re all fairly sure Obi-Wan has been stealing everyone else’s. Does that mean Obi-Wan has the most brain cells? No. Because he drops one every time he loses his robes, which means dumb little shinies and random animals find them when he’s lost them and decide to keep them, therefore, becoming smarter than him. Obi-Wan has the second lowest brain cell count in the order. Who has the highest? Ahsoka Tano. She has THREE whole brain cells. Three. The council didn’t want to give her to Master Kenobi because they were afraid she was gonna turn into a moron like the last kid they gave him.
Rex has the same number of brain cells as Anakin at all times, but positive instead of negative, which fluctuates, depending on the time of day, if Padme is nearby, or how curly Anakin’s hair is today (usually effected by humidity.) He has the second highest count in the GAR.
