"You are not how I remember from class, like not at all," Aaron points out disbelievingly, inspiring chuckles from others in the room.
But it's not all smooth sailing: At one point, Paul forgets a line of dialogue and curses lightly as the woman reading opposite him jogs his memory.
"Some straight like you with a giant stick up his ass, all of a sudden age, what, 50? You're just gonna break bad?" he says, delivering the full line (from which the show gets its title) correctly.
There are also lines that seem ironic in hindsight, considering how White's simple meth operation has spiraled out of control over a year's time.
"If you've gone crazy, or depressed, uhm, I'm just saying - you know, that's something I need to know about. Uh, that affects me," Aaron says (if only he knew what's to come).
Paul's stilted pauses in the reel would go on to become a signature vocal styling for the character, who has become a fan favourite.
But many viewers would be surprised to know that showrunner Vince Gilligan planned to kill off Jesse in a botched drug deal at the end of the first season.
It's a good thing he changed his mind - the character has become a complex, critical part of the story arc, and Paul's performances have garnered him two Emmy awards for best supporting actor, with another nomination for 2013 pending.
