Design a Banner

A coworker bought the small espresso/latte mug from a NY airport a couple years back. To say that he LOVES this is an understatement. An intern made the mistake of using this mug for a morning espresso and the results were hilariously disastrous. We'd like to make pull a prank on our dear friend using his beloved mug as the center of the prank, We have lots of ideas and they include, but are not limited to: - Creating a series of mugs that have just 1 thing wrong on. Ex. just 1 heart would be upside down or 1 NY upside down - Creating 20 mugs, each a slightly lighter shade of red until it becomes pink. Every week we'll replace his mug with the next lighter shade. One day he'll wonder what happened to his mug. - Create an exact replica mug but change the word after <3. Examples include "I <3 users" "I <3 tmblr" "I <3 kifi" "I <3 Effi" or the text in Hebrew Can you please help us make our coworker pay for his irrational attachment?? I tried to design this myself on Zazzle and I can't get it close enough in the first 5 minutes that I explored the site. Are there other sites that you know of that can do this? Or can you make it happen on Zazzle :)
