A student goes into his lab right at the end of the class hour.
Fearing he’ll get an “F”, he asks a fellow
student what she’s been doing.
“We’ve been observing water under the microscope.
We’re suppose to write up what we see.”
The page of her notebook is filled with
little figures resembling circles and
ellipses with hair on them.
The panic-stricken student hears the bell goes
off, opens his notebook and writes, “During this
laboratory, I examined water under the microscope
and I saw twice as
many H’s as O’s.”
