Here's his winning entry:
How are skull and a shamrock the same
other than the letter beginning their name
One symbolizes luck
the other un-luck
But only a skull looks cool while aflame
As always I was blown away by how creative and clever all of your entries were and I was so glad I didn't have to try to pick a favorite, so thanks to Random.org for doing the job for me!
And thanks again to everyone for participating, just because you didn't win doesn't mean you can't get a Shamrock Skull Shirt of your own from www.StPatty.biz!
And stay tuned for more contests in the near future!
