I remember an old funny advert from an Amiga magazine (Amiga Format I think) where you could see Lemmings taking over an advert for Awesome (which is featured as a cameo level in the original Lemmings). I couldn't find the ad on the internet, but I found a photo I took of the advert many years ago, so I figure I'd show it off here. I also included a normal Lemmings advert for comparison's sake.
That's really funny. Great find.
