friend:  'why are you laughing?'

me:  'i'm not laughing...  i was about to sneeze, i suppressed it...'

friend:  'why did you suppress it?'

me:  'i don't want to sneeze inside the car...  the germs will be confined inside...'

friend:  'cover it with your hands...'

me:  'i don't want germs on my hands...'

me:  'i don't want the germs on my skin...'
