Bullets in schools, the eeeeek level explained

Eeeek Level One.  Sammy might actually get away with this one because lead-headed teachers and administrators are probably unaware of the very useful "bullet" pencil.

Eeeek LevelTwo. This one will cause a lockdown and local editorials praising Superintendent  Z. T. Limply for taking no chances. After all.  if it saves just one life...

Eeeeeek Level Three:   If you feel like amusing yourself with a full SWAT, active-shooter routine, complete with horrified mothers on MSNBC  (and even more horrified interviewers), you could slip one of these into some rotten kid's back pack.
