Fortunately, the first time my grandpa mentioned "guerrillas" in Central America to me, he explained that they "weren't like gorillas at the zoo", they were people, and it was spelled differently, so I didn't have that confusion.
But when I heard someone mention "guerrilla tactics" in a cartoon, I thought it meant fighting like a gorilla-- beating your chest and all of that.
