horns

As far as marketable skills go, this is dubious. That said, a good horn impression would be the perfect thing to do if someone's obliviously standing in your way. Now just imagine hearing this a foot behind you while walking down the sidewalk.

If you're a fan of classical music and also the loud jarring sound of an oncoming train's horn, then oh baby is this video for you. Pachelbel's Canon in Train.

Just the idea of this is hilarious. The timing couldn't have been worse, and for that we have a glorious fail on our hands.
