Birthday partaaaay

Charlie and I were recently asked to create a birthday invitation for a couple of very special birthday twins, to the theme of Doctor Seuss. The brief was really open ended, which basically meant I could design whatever I wanted. That was the easiest part. The hard part was realising what's Doctor Seuss without a really cool rhyme to go with it? I was completely stumped and didn't come up with anything more then a line long, but Charlie came up with this rhyme out of nowhere, and we had our invite!
