Editor's note: Do you need something to smile about? Every day, WND selects the best joke offered up by readers and contributors to its Laughlines forum and brings it to you as the WND Joke of the Day. Here is today's offering:
I was teaching my chemistry class about elements on the periodic table, mentioning that since silicon and carbon have similar properties, science-fiction writers theorize about silicon-based life forms on other planets.
"But," I stressed, "there is no evidence that silicon-based life has existed here on Earth."
A girl in the class snapped back, "Have you ever seen Baywatch?"
