Goldberg at one point considered sueing the makers of Mouse Trap for copyright violations, but turned out Goldberg was too old to give a rusty goshdarn.
In 2006, the game was re-released in the United Kingdom with a completely new design in which there are three mousetraps, and in which the board and plastic components are completely different. The most obvious change is the addition of a model toilet at the top of the tallest part of the game. Another key difference is that all of the mousetrap is set up in advance of the game.
WHAT!? Sacrilegious!
