Sorry if this has been posted about before.
I was sitting around, idly watching some cartoons, when low and behold, I see SAM AND MAX in the background! It is in an episode of Foster's Home for Imaginary Friends on Cartoon Network, the one where Bloo throws a 'wild house party', I believe the episode is even called 'House Party'.
They are about 4 minutes into it, when Bloo is walking through the crowd and greets an upside down friend "How's it hanging, Hangy?" You can clearly see our favorite rabbit and dog in the background drinking punch.
I was really excited about this for some reason, and it got me wondering if people knew other cool cameos of the dynamic duo (I know about the Jedi Knights one, and the map that was in the shape of Max's head.):D
