Sound designer, mixer, dialog editor, engineer, composer. Since 1986. Microphones, keyboards, software, hardware, sound effects, foley thingies, music thingamajigs, voice doohickies, crashes, booms, explosions, subtle air movement, fart sounds (see previous), lovely music, and bad jokes. Oh, and puns. Lots of puns. The kids these days call them "dad jokes', but really, they're puns.
