Have you ever dumpster dived and why did you do it? Would you for the right reason?

I bet my friend 2-12 packs of Corona...We stoped in back of the alley....He pointed at a dumpster that was already open....So i ran and jumped in as high as i can....( that was a big mistake )....There was 2 cats in it...and i got F-in scratched in the F-in Freak-in face, head and arm! That's not to laugh about....it hurt!
