Funny Coffee Mugs 

This design is available on all the coffee mugs at Zazzle – choose from seven styles including this awesome travel mug that come in white and silver.  There are dozens of colors to choose from.  My favorite is the morphing mug. It is black but when hot it turns white and you can read the print.  This design will look great on it. Who cares if you take my cold coffee. When it is hot, keep your bloody hands off.

The morphing mug changes from black to white when hot liquid is added
