Hairpiece

Can someone please point me to something with Kristen Wiig in which she is funny? I have only seen a few things featuring her, and she is always the weakest part. I just saw an imitation of Madonna she did and it was painfully unfunny. I have seen her in a few things that were funny, but not the parts that she did. Her main skill seems to be saying/doing something awkward and staring at the camera or otherwise holding up what we'd like to see from happening. Yet, she is being heralded as the new Tina Fey. What am I missing?
