During college, my girlfriend at the time was driving me around her hometown in New Jersey. We came to a fenced area surrounding an AT&T building. There were telephone poles of varying heights stuck in the ground and they were covered with what appeared to be varying types of oil or other protectant. "That's where they grow telephone poles", she said. I burst out laughing, thinking she had made a very funny joke.
"Why are you laughing, " she said straightfaced.
Turns out her father told her this fib as a little girl - and to that day she still believed it!
