A six-second voice clip where a speaker flatly says 'Nah, who needs it anyway' like he is shrugging off a broken radio he wanted to use. It feels dismissive and quietly funny, the sound of giving up without getting upset. The clip comes from an SFM animation, with original audio credited to DaFuq?!Boom!
