How many chemists does it take to change a light bulb?
Here at the American Chemical Society in Washington D.C., not only are we experiencing a heat wave (95 deg F today), but that all important question is burning on my mind and with ACS celebrating 25 years, I am not any closer to finding the answer.
So, how many chemists does it take to change a light bulb?
I’m afraid to say my world-renowned British wit fails me today, and I can find no humourous response.
Does anyone out there have a decent punchline?
All answers on a postcard to booth 629....!
