Display Welcome message with current user's name on a Dashboard



I have a dashboard with many "Current User" reports. I would like a message on top of the dashboard to appear that says "Welcome" and then the current user's name.

What's the best way to go about doing this? I don't want to pull a report that has the current user's name on it because then you see the column header and grey column and row lines... I'm assuming I need a metric widget, I'm just not sure where to pull the name from, how will it change based on whoever is currently viewing the dashboard?
