MadTV character question

This is really just a general question, but since it’s about a TV show I’ll put it here.

Does anybody know the name of the super annoying middle aged female character on MAD TV or the name of the actress who plays her? (This is the character who was on WHO WANTS TO BE A MILLIONAIRE, drove a guy holding a yard sale nuts over a box of tacks, destroyed an “all you can eat” buffet in Vegas, etc.)

I think that’s Mo Collins. The character is Doreen Larkins.

You can flip through Mo Collin’s chararacters at the bottom of that screen.

Thanks. (I have a customer who could be her twin in both looks and personality and was trying to find some images of her.)

Actually, the one I was thinking of is Lorraine, but she’s also played by Mo Collins. Mo’s name let me get the character.

Thanks.
