Sierra Online Adventure Game cameos

[SlickRCBD <slickrcbd@nospam.com>]

I was just having a talk about the movie Blues Brothers, and mentioned 
the cameo of Jake and ELwood in Space Quest 1 (in the bar with the slot 
machine and live bands). That lead to a discussion of Sierra's other 
graphical adventures, and trying to remember if there were any other 
cameos. The only one we could remember was the Batman cameo in Kings 
Quest 2 (outside Hagatha's cave). Were there any others that anybody 
else can remember?

I can think of a few similar things, like in Police Quest 1 you get to 
visit the outside of the Disco from Leasure Suite Larry 1, and Leasure 
Suite Larry 1 had the Moose head from Kings Quest 3, but their not the 
same kind of cameo as what I was looking for.
