“I saw a microbiologist today. He was bigger than I imagined”

A “microbiologist” is not a very small biologist, but there are jokes.
   
“I saw a microbiologist today, He was bigger than I imagined” was posted on Twitter by Pete on January 2, 2017. “I saw a microbiologist today, He was bigger than I imagined” was posted on Sickipedia on January 3, 2017. (This was possibly posted before the January 2nd tweet because of time zone differences.) “I saw a microbiologist today, He was bigger than I imagined” was posted on Twitter by 🎗 MOGGY 🎗 later on January 3, 2017. The joke probably originated on the Sickipedia website.
