Is there any samples in just dance by Lady Gaga?

Having not bought the CD (and being unable to find attribution on the web), I can't verify whether it is actually credited as a "sample", but the first line after the intro in the song ("I've had a little bit too much...") is a direct musical lift of the opening line of U2's "Sunday Bloody Sunday" ("I can't believe the news today..."). In addition to the driving beat, this might account for the familiarity and immediate lyrical acceptance of Lady Gaga's smash hit.
