John IRL
In real life, John Ross Bowie can say Ls and Rs with no difficulty. Out of the TBBT universe, John has found plenty of work in Hollywood to keep him on his toes. He initially started out as a comedy writer, coming up with unique routines that would amuse audiences around the state. John eventually caught the attention of higher-ups in Hollywood, and the rest is history.
After the series finale, John has starred in two movies (Jumanji and Bad Therapy), and quite a few TV shows, including Speechless and Big Hero 6. Before you ask, no, John Bowie is not related to the late David Bowie.
