My sister Wendy forwarded this to me this morning - via SomethingAwful.com. I always love it when people see something like this and they immediately think of me!
How awesome is that? I would totally be buying that if it were an actual product. Nice touch with the "now with splatter pack!" Other pages probably include the secondary jaws coming out - (probably with saliva dripping all over the page) and Sigourney Weaver famously in her underwear at the end of the film.
It's almost not cool to like Alien anymore, but I am hard-pressed to come up with a movie monster into which more thought was given to its life cycle.
