I spent a few years in LA going to auditions. Some of the roles i got cast in include overweight jogger, fat guy with beard and guy waiting in line for donuts (which was actually not a specifically fat guy audition more a hipster which was also a lot of the roles i went out for.
It wasnt that awkward. And i got to know a lot of dudes who kind of look like me just from seeing them at the same auditions.
Most awkward audition was for a Polish tire commercial where i had to be topless.
