Friends - How You Doin?

This mug is from one of my favorite TV Shows, FRIENDS.  The mug appears totally black on both sides. On the right is the iconic phrase used by one of the show's characters (Joey) "How you doin?" and on the left, at the top is the F·R·I·E·N·D·S Logo. 

 When hot liquid is added, the black area clears to show a green background with a drawing of New York city, where the show took place.  The NYC design runs all the way around the mug. 

It even has it's own full color box!
