Rusty Paid Homage to One of Chevy Chase's SNL Gags

During the scene when Chevy's lights on the house fail to work for the first time, Clark asks Rusty to double check the lights for him. At that moment, Rusty looks at a non-existent watch on his bare wrist. He pretends to check the time and then excuses himself to go inside.

This was a classic move done by Chevy Chase frequently when performing on Saturday Night Live, so it's no surprise that they added it into the movie for a similar effect. It was also a nice Easter egg for SNL fans.

The Cat Electrocution Almost Didn't Make the Cut

While trying to plug the lights into the Christmas tree, Clark accidentally ends up electrocuting the cat and killing it. Although no cats were harmed in the making of the film, the scene was almost cut before its release. Warner Bros. executives wanted the scene cut for fear of offending some viewers, especially animal rights activists.

Producer Matty Simmons then convinced the Warner Bros. executives to leave the scene although they hesitantly obliged. As it turns out, after the first test screening, the audience claimed that the cat electrocution was one of the funniest scenes of the film.
