I opened this right as I was watching her do the 'Obama is a Muslin' lady on weekend update thursday. I could see if any one of her sketches was turned into a Waynes World type thing, it could get ridiculous (I worried about this when she started out a while back with that Target lady), but she is aware enough not to go over that line, I think, not to mention she's funny as hell.
It seems to me that the new age of snl has shaped her in a way, it's like she came to quickly realize the "It's Pat!" kind of sketch is boring and the fastest way to annoy people.
