Replying to Bag of shit

the other day my friend's little borther shit into a bag(i have no idea why) and we saw him and stopped him and asked what was in the bag and he said poop haha, sooo (we were a bit high) we gave him a lighter and told him to light it on someones porch, i know it was assholeish, my bad, so he lights it and rings the door bell and runs and we were hiding behind a bush. so the guy opens the door and hes like OH SHIT! and he gets water and puts it out, after it was thuroughly burned though, so then he starts to smell it and hes says to someone inside i "i think its poop" and then my friend said haha he called the shit poop ,it was straight out of billy madison and it was soooooo funny
