It's a trap!

I have long pounded my head against a wall trying to figure out how to do a worthwhile trap counter.  There are many good examples out there of spike and spear traps but they did not quite do it for me. Then two weeks ago I was in town with my daughter by a local cafe and we passed a piece of cake on a plate sat on a sign.  We both looked at each other and said the same thing.  Don't touch it it's a trap!!  That got me thinking about what else I could use as a trap marker.  This is what I came up with. 

Box trap

Cake trap

Pizza trap
