Hank takes Bobby to the doctor to get him some testosterone supplements to jumpstart puberty. Hank in turn is the one to actually use them (unwittingly at first since Peggy slips the testosterone into his food and drink). The dosing causes him to basically go through puberty all over again. To make things worse, Hank volunteers the city to have a sponsored run with the bulls event while on the drug. Shortly thereafter he ceases usage of it altogether and must run without aid of extra energy making things difficult. Bobby faces failing gym because he's too embarrassed to shower with the other guys.



  • The title of the episode is an obvious parody of Marvel super hero "The Incredible Hulk".
