The Instant Mini Jack-o-lantern Army (made of citrus!)

Step 4 Get Creative

What makes these really fun is that in a small amount of time you can create a massive and varied set of jack-o'-lanterns with very little effort. So go for it. Try to put some personality into your 'pumpkins'. You can stick to traditional halloween designs, or branch out based on your own aesthetic hankerings. If you're headed to a party or a potluck, you can draw your friends their own jack-o'-lantern. Inside jokes, memes, characters - there's as much material at your disposal as for traditional pumpkin carving!

Also go for as big a sample of oranges as you can. The set pictured in this instructable wasn't so large (had a cold and ate most of them before finishing :P) but you can sort of get the idea. A big bowl of oranges, each with an individually unique face makes for a great amount of fun.
