Rainbow Dash ordered milkshakes for her and Pinkie at the Sweet Shoppe just like any other normal day. However, she and Pinkie had an argument over how signs always tell you what to do after Pinkie made a smart remark on why she didn't wash her hands. Things proceed to get weirder and weirder as things progresses.

Again, inspired by Nathan Doan, again, and I don't have original ideas...
