1. Being on the bus, tearing down the busway at 100km/hour and the bus driver have a sneezing fit.
  2. Eating my lunch in a cafe and having some random guy come up to me and scream in my face, "What the fucking fuck is wrong with my back?!!!"
    Not sure dude, but getting away from me will ensure you sustain no further injuries.
  3. Hearing the sound of broken glass as I walk past some glassware in a shop.
    Thankfully it wasn't me but it did freak me out for a bit.
