The Fat Mentality vs. The Thin Mentality, Summed Up In One Conversation

I was having a conversation with two female co-workers, both of whom are in pretty good shape, when an actress walked by in a dress that was extremely flattering.

Co-worker #1: Wow, she looks great. (pause) I need to work out more.
Co-worker #2: Yeah, me too.
Me: (pause) I want a Twinkie.

Suddenly, my obesity became far less mysterious.
