Mistaken Identity

So ummm am I the only person that constantly mistakes Leslie Mann, Julie Bowen and Elizabeth Banks for one another? I can't be.

Looking at their pictures I can easily tell them apart but whenever one of their names gets mentioned or I see one of their pictures I always have to think about which one of them is being talked about. I'm not really sure why this is. Is it because they are all blonde, pretty comedy actresses?  What about Amy Poehler or Christina Applegate? I can easily tell which is which. Anyway. Maybe I just exposed how dumb I can be, but this has been bothering me for a while.
