Maybe it is me, but I get Megan Mullally and Molly Shannon confused all the time. So much so, I was beginning to think they were the same person just like Isla Fisher and Amy Adams. Turns out they are not because the actress that was on Will & Grace Instagrammed a video of them together. Proving they are indeed different people. Now can someone please tell me which is one which so I will be able to tell them apart in the future?
