The real story regarding Sheldon's '73' tee shirts and interest in the number 73 is simple. He is friends with Canadian astronant Chris Hadfield. Chris is a 'Ham Radio' operator who sent the '73' tee's to Jim Parson. Chris' ham call is VA3OOG and was very active while working on the space station. Hams always end each conversation with '73', which means 'Best Regards'.
