Growing up in Southern California there was an auto dealer named Cal Worthington and his dog spot. Now spot could be a bengal tiger, a monkey, whatever, so it's already confusing right? Well there was a song on the commercials advising you that, "If you want a car or truck GO SEE CAL" but since it was so fast and I was already confused, I thought the song was, "If you want a car or truck, PUSSY COW."
And it sort of made sense with a lion sitting on top of a car. I've talked to alot of friends who thought the exact same thing when they heard this commercial.
