I love correcting people when they use poisonous. One of the girls at work was like we saw a poisonous snake today. I'm like what? She repeated herself, and I'm like poisonous? Then she's like yea poisonous, so naturally I'm like venomous. Then we go back and forth so I decided to educate her on the difference.
Then when I see people say the only good snake is a dead snake, I usually make some remark to upset them. I hate idiots.
