The line comes from JonTron, the YouTube comedian known for exaggerated reviews and parodies, and his video built around Flex Tape, the advertised waterproof repair tape. In the episode he leans into the infomercial format, testing the product in increasingly absurd ways, and the phrase stands out because it sounds like a straightforward suggestion delivered with comic scepticism. Clipped from that review, it travelled as a short reaction sound on soundboards and in video edits, where creators reuse it to puncture overthinking. Its staying power comes from that simple, reusable setup: a dramatic problem, then one dry, obvious answer.
About this sound
JonTron says you could do that in his Flex Tape video, a short sarcastic reaction clip used to mock obvious or unnecessary solutions in edits and memes.
This five-second clip captures JonTron delivering the line you could do that with deadpan, slightly mocking disbelief during his Flex Tape parody, where he tests the famously over-the-top waterproof tape. His voice is calm and conversational at first, then lifts into a knowing, sarcastic emphasis that makes the obvious suggestion sound both helpful and ridiculous. Listeners hear it as a punchline rather than genuine advice, because the delivery implies the solution was staring everyone in the face. In an edit, it lands as a quick, dry reaction that undercuts a dramatic setup and lets the audience laugh at the absurd simplicity of the fix.
