My vote is for #3 - THE PERFECT PICKLE SURPRISE!

These funny food costumes can be found on the following sites. If you are crafty, like little Jr., then maybe you can whip one up at home.

Other fun ideas could be Betty Crocker (like Blonde Appetit herself!), Alice-in-Wonderland and hand out Petit Fours with Eat Me on them and mini-bottles that say Drink Me, Spaghetti and Meatballs made with Yarn and such, a sexy chef, a Waffle House Waitress, a naughty banana, Green Eggs and Ham, a six pack of beer with your buddies, a hunter and a deer (venison is food...right), Iron Chef, and more.

I really like the following link for homemade food costumes: Pig Spit, Smores, and Sushi all make me laugh. Really creative!
