i spit of the lift when ppl arnt around, because its disgusting and not fun to be spat on, but my friends have what they call the gaper challenge, where you get points for hitting gapers, different areas are worth diff amounts, highest scoring spot is the gaper gap, and bonus if they fall, keep score and at end of season see who won.  i think its really a dick thing to do, but at the same time i cant help but laugh a little.
