It's everyone's worst nightmare. . .come true!
Jake Sherman used to be your average, ordinary twelve year old, until he became a completely different person. Tall, skinny, balding, nerdy. . .OH NO! Jake's turned into his weirdo teacher, Mr. Dirksen!
It's bad enough that Jake's an adult now, but a teacher? The geekiest, most made-fun-of teacher in the whole school? Jake's sister Jessica is the only person who'll believe him--and even she's a little suspicious.
Jake and Jessica better find a way to get things back to normal fast--not only because Jake's going crazy, but also because dorky Mr. Dirksen is running around in Jake's body! The nightmare is only beginning!
