Not sure the audience are deaf. Deaf people don't laugh, as it is sound related, instead they make a "jazz hands" like sign. Apparently is really odd if you are doing stand up comedy through a translator...

Laughter is an involuntary response, you twat. They don't applaud, instead doing the jazz hands thing.
