“Toonces The Cat Takes the Wheel” premiered on “Saturday Night Live” on May 20, 1989.
Here’s more from Wikipedia:
Dana Carvey and Victoria Jackson play a couple who allow their pet cat Toonces to drive their car; Toonces subsequently drives the car off a cliff.
Toonces was the family pet of Lyle (Steve Martin in the first sketch, thereafter by Dana Carvey) and Brenda Clark (Victoria Jackson), an enthusiastic couple who would allow their cat to drive the family car. At first, they were delighted that their cat had such an ability, but were always horrified to discover (too late) that Toonces was actually not a skilled driver at all. The running gag was the punch line: “See, I told you he could drive! Just not very well!” Inevitably, Toonces would drive the car over a cliff whenever he got behind the wheel. This sequence was characterized by someone in the car yelling “Toonces, look out!” with the Toonces puppet appearing to scream also, followed by the car falling off a cliff, and sometimes exploding (as shown in a series of stock footage scenes—sometimes the same one used multiple times within a sketch).
Toonces was portrayed by a live cat (for the title sequence and certain close-up driving scenes) and a puppet. The puppet was made up of three parts. The first part was a head and torso piece, which was a simplistic rendering of a grey-and-white striped short-haired tabby. The other two parts consisted of two separate paws, which were manipulated so as to simulate Toonces actually steering the car.
