The secret to a good prank is that it’s clever without being consequential — like a Christmas prank war, or making a scene in a Jamba Juice. Aaron Paul learned this the hard way when he promised Breaking Bad fans a Jesse Pinkman spinoff (in his defense, he was bored). Now, nearly a year later, he is still haunted by his guilt, as he confessed on Jimmy Kimmel. It’s like he’s still dealing with the emotional fallout from participating in a massive New Mexico drug enterprise — except, of course not nearly as bad.
