A childhood belief about condoms

In 2nd grade we were studying spelling words and on the list and one of the words was "condominium" (i think that's how you spell it). I thought the meaning was the meaning to condom, and that it was just a typo. Soo...it got my turn and i had to stand up and spell then give the definition of condominium; i spelled it c-o-n-d-o-m. and said this for the definition, "i'm not sure what the meaning of condom is but you put it on hoses"
