I remember that skit. It was funny.
Here it is again for people to watch:

Anne does a really good impersonation of Katie. She's got the mannerisms exactly and her voice is pretty close too. That's pretty awesome to be able to embody someone else like that.
Anne is just a really fun girl.
Did I read correctly that Tom Cruise and Katie Holmes actually boycotted the oscars because of that? Ha. Well it shows they have no sense of humour if that's the case.

t:
Maybe Anne as Selina should do an impersonation of Katie Holmes's Rachel Dawes in TDKR just to annoy Bruce Wayne. That would be really cool if she did. It would fit in perfectly with her naughty personality and would be as if she has no regard for the dead. Of course, that would pose a slight continuity problem with TDK since it was Maggie Gyllenhaal last time and one might wonder why Selina is going back to the original incarnation, but it would be funnier (and probably easier) to mock Katie Holmes in TDKR than Maggie.
