Icon Tip of the Day
Another example below. Let's say Matt replaces his icon with one of his idols, the Olsen twins. (Not a huge stretch from reality).
If you tell him an off-color joke like this, people will be like, "Eww, you sicko. Why are you saying stuff like that to Mary Kate (or Ashley) Olsen?" Then they will ask you which one it is, and who can tell them apart anyway? You get my drift. It could get bad. Tell your friends with a penchant for misleading buddy icons to knock it off!
