Funny Mole Day Jokes and Humor

Chemistry Cat meme about moles.

Mole Day is October 23 from 6:02 a.m. to 6:02 p.m. in honor of Avogadro's Number (6.02 x 1023). A mole is a unit of measurement used when existing measurements are inadequate and its particle measurement is based on Avogadro's number. Like Pie Day which is celebrated on March 14 due to the fact that it mirrors the pie number, Mole Day is celebrated on either October 23 or June 2 due to the dates being similar to Avogadro's number.

What better way to celebrate a holiday born out of chemistry humor than with jokes?
