Glenn Howerton on A.P. Bio (2018)

Episode 7 of the NBC comedy A.P. Bio got leading man Glenn Howerton shirtless again this week. His character, Jack, neglects his teaching duties in order to write a book to upstage his successful college pal Miles. He is so interested in his book that he even writes notes while showering. He's shirtless for that scene. He's shirtless again later in the episode as he hits the shower again, while dealing with a lack of hot water. He's interrupted by a call from Miles, leading him to stand around wearing only a towel.
