-when you put the wrong end of the pipe into your mouth and burn yourself (my friend did this)
-you light a joint and it sets on fire and burns ur face and you dont notice until after ur hit (I did this)
-you stare at the T.V when its not turned on....
-when you dive for the lazyboy and miss it
-try to run up the down escalator (wait a sec i do that wen im sober

)
im all outa ideas for now.
