(Though Howerton might be perfectly fine as a high school teacher.)
And similarly to how Kaitlin Olsen’s role on The Mick offers reflections of It’s Always Sunny’s Sweet Dee, a bit of Dennis’ unencumbered pride shines through in A.P. Bio’s Jack Griffin, a Harvard graduate who (after a rival philosopher gets his dream job) slums it back to his hometown of Toledo, Ohio to take a gig as a high school biology teacher for advanced placement students.
He’s definitely not alone in gaining pleasure through these particular kinds of self-centered characters, which is proven by the hordes of It’s Always Sunny fans who adore the master-creep Dennis more than the Gang’s other misguided characters.
As Howerton implied, Jack is a very smart person when it comes to certain issues, but he’s a social and emotional mess, and the part feels tailor-made for that section of the actor’s skill set.
