Taking out the trash

Today the trash was looking a little full so I decided I should probably take it to the dumpster.  As I was walking to the elevator I realized the bag was leaking Dr. Pepper.  Why would such a thing happen?  My roomate likes drinking Dr. Pepper in cans.  However, he never finishes them and puts them in the trash can anyways.  When I got back to the room to put a trash bag back in the trash can I saw that the bag had leaked all over his clothes.  I told him what had happened and he just laughed about it.  I can only hope he starts drinking all his Dr. Pepper from now on!
