I remember one time I had to throw one of the those long mirrors in C and D into the compacter. I threw it as hard as I could and it felt so good to hear it crack and break upon impact with the wall. It was even better when the compacter's arm crushed it and all I can hear is glass breaking and shattering.
The only good thing about emptying those stupid cardboard 4 way displays at Walmart is tearing them apart as I put them in the baler. I call it anger management. It can take a while sometimes because the companies use strong glue or double-sided tape to hold the pieces together.
