When I was about 11, my mom had this doberman named Scarlett. She was a real pain in the ass. She barked constantly, hated kids or anyone else that might have been on our lawn, or even walking across the street.
Anyway, so mom had set a baby gate in the kitchen doorway to keep the dog from wandering throughout the house.
It was halloween, and of course trick or treaters were ringing the doorbell. This dog was going nuts in the kitchen, barking and pawing at the baby gate until she knocked that sucker over. She managed to get past my dad at the doorway, and chase all the trick or treaters away. One kid dropped his sword as he ran like the dickens.
I know one of those kids could have gotten hurt and they were probably scared to death, but picturing that and my parents freaking out is still so damn funny. My stomach hurts from laughing.
