Full-sized Lego man

  Korean construction workers bust these guys out when then need to nip 'round the corner for a wee dram of soju.  No one usually notices.
  When I was in grade one, a classmate helpfully suggested that I try to eat a piece of blue chalk.  I abided, and chomped away on the chalk.  After eating maybe a third, I saw the teacher coming, and ditched the chalk.  She stood over me, and asked "Were you eating blue chalk?"  There was blue chalk all over my face and lips.  I looked at her, and said "No." in an innocent little voice.  The moral of this story is that it tasted better than white chalk.
