This kid I know bought himself a rottweiler puppy a few months ago. You need to know that for the story to make sense, trust me. Anyways, the other night, he thought it would be fun to do some mdma with some of his friends. So, he took a half tab and, sure enough, after a little while he started to trip out. Being the winner this kid is, he couldn't handle the high and ended up vomiting all over the place outside.
After going inside to lay down for a while, it occurred to him to check on his dog, and upon doing so he discovered that the dog had eaten all of his vomit. The kid and his buddies take the dog inside to keep an eye on it and before they know it the dog is whipping its head to and fro like a retarded kid that can't get his helmet off. They started playing with the thing and it wouldn't let them stop. It even started humping everything in the room.
Eventually, they decided to take the animal to the vet and tell him that the dog ate some unknown poison. The vet clued in and told them to come clean so he could help the dog. They ended up pumping its stomach.
I laughed very hard when I heard that story.
