One after the first sentence, one after the second sentence, and then a stack of seven at the end. Totaling nine.
Even if you separate them out ignoring the first two as being separate instances of sarcasm, the last section is still an uneven number.
EDIT: People please don’t downvote this person over misreading the number of /s in my post. Not justified. They made a simple mistake. You could just simply not upvote if that’s how you feel.
