Jim Carrey's stand up comedy routine "An Unnatural Act" is on youtube

Go there to see part one, part 2 and 3 are also there.
This one runs for around 27 minutes. Though someone in the comments section had posted that Jim performed the same routine in Canada and was 45 minutes long. So even though this is the complete act, there is apparently 15 minutes more, which as "The dog and glass of water in it". Isn't that just his stand up comedy at the comedy store?
