This week's contest took around 10 minutes to solve.
Grand Prize: GIANT
2nd Prize: HA HA HA WHOOPS
3rd Prize: SHIRL
For a list of the differences, see the comments section of the previous contest post, wherein I posted GIANT's winning entry. Congrats to the winners and thanks to all who played!
One funny thing: I noticed while judging the entries that there were actually 16 differences, my mistake, so I awarded anyone who listed 15 correct differences. For obvious reasons, everyone stopped looking after they found 15. Doesn't change the contest any, just makes it 1/16 easier to win, I guess.
Next Thursday, another contest! WOW!!!
