It seems as though XtraNormal is a venue for profane ranting. Check out these four videos. All have curses.
iPhone4 vs HTC Evo (16+ million views, profanity)
The Joy of a Salesman (2+ million views, profanity)
Anesthesia vs Neurosurgery (350,000 views, profanity)
TweetFired (200,000 views, profanity)
The fifth video switched to “Private.” Sorry ’bout that.
