Replying to crazy drunk guy

ok, there was a guy tonite, that was at our dairy queen(he was homeless drunk and had a dog). me and some friends were waiting for another friend to get off of work. meanwhile, we were talking to this homeless drunk guy and he was saying all of this bull shit, lying. then he is like do you want to see something cool we were like ok. so he lit this cup on fire with rubbing alcohol in it that was sitting on top of a garbage can, then he poured some more on and it cought the garbage on fire, so he tried to wipe it off and it lit his longsleeve shirt on fire, and he was running around. we got the fire out eventually. then when my friend got off of work, he decided to give this guy a ride to walmart, which is on the other side of town, cuz we felt kind of bad for him. then when we got there, he started walking towards the doors and his dog, which looked like lassie but only about as tall as your knee, wasnt walking as fast as him so he picked the dog up and threw it down on the cement, while he was yelling at it, and the dog was scared to death of him. me and my friends were shocked, cuz he was cool when we first met him. then we were like leave the dog alone, the he said shut the fuck up it is my dog, the he picked it up again and threw it down(no bullshit drop or anything, this was a hard ass throw). so we drove to this resturaunt and called the cops on him.
it was freaky, i wanted to kick that guys ass. i cant get that out of my head now.
