Cingular patents emoticons

Sometimes, I really don’t understand why people patent the things they do. Cingular has gone and patented:

The method and system described in the patent allows a user of a mobile phone (or other device) to select a displayable icon, such as an emoticon, that indicates the mood or emotion of the user or conveys other information independent of text. In some embodiments, the selected displayable icon is inserted into a text message or screen, such as an instant message, chat screen, or user text field.

US Patent US2006015812 is so amusing since there’s potentially way more prior art than ever possible not to mention that AOL already has a few patents regarding the emoticons.
I want to know what genius wasted company funds to apply for that patent. ^o^
