At this point, Mac DeMarco is probably just as well-known for his prankster persona as his music, and it seems that these goofball antics are not a recent development. A Stereogum reader shared the following video from a friend who claimed to have played an online multiplayer with DeMarco a decade ago. We reached out to DeMarco’s reps for verification and haven’t heard back yet, but it sure looks like him (albeit with floppier hair), and this is definitely the kind of thing I’d imagine a teenage Mac DeMarco would be doing. (UPDATE: DeMarco’s spokesperson confirms it’s really him.) Watch him sing a ridiculous song and make ridiculous faces below, and note the subliminal image at 16s.
