Here's a free game I found where there are Lemmings inside that you must kill:
Blip & Blop - Balls of Steel (http://www.loaded-studio.com/blip&blop.php)
Look at the third screenshot.
Bwahaha. The game looks good in itself... Might have a go once I get home.
The ultimate question: Shall the lemmings be saved or killed?
EDIT: The ultimate ultimate question (Part I): What is the question that goes with the ultimate answer (you know, 42).
The ultimate ultimate question (Part II): What happens when both parts are known in the same universe?
The two are mutually exclusive, knowledege of one precludes knowledge of the other. If both are known by one person, the universe would disappear and be replaced with one something even stranger. Some say this has already happened.
Some say it's also a ruse devised by a cunning editor of the Hitchhiker's Guide to the Galaxy in order to boost sales of the book, because it is the only publication in any galaxy with the words Don't Panic printed on the front cover.
hehe...
I decided to edit that post a while back to make it funnier, and that's why I put those in.
