503 clips, some of which weren't even swearing. Counted 13. So that's 490 swears, in 12 hours or so of gameplay, not counting alternative choices that result in swears. So let's just say twice as long if you count alternative choices, since a large bit is unavoidable, but there are typically four paths. 24 hours x 60 (minutes) is 1440, which means there's roughly one swear every 2.94 minutes. Not terrible...bad, but not terrible.
More did it because I was curious than anything. I still love the video.
