Why its the last season???!! Well!! It clearly seems, Chuck Lorre now finally it seems has good sets of writers, he is churing out some really good episodes here, as also in his other shows like "MOM"..
Now they decide or rather, "Sheldon" decided for him to end the show. Although; it will end on high note, and it will never be at par with other good sitcoms cause of its track record, but it can be something more.
This episode by far was best episode of the #Bang I ever watched in this series.
I dont know maybe the network could change #Sheldon's mind. And it should continue IMO.
Peace out bros!!
