From Introvert Retreat:

Question / How many introverts does it take to have a meeting?

Answer / It only takes two but they both need to have a computer and an internet  connection.

From Finnish Jokes:

How can you tell the difference between a Finnish introvert and a Finnish extrovert?                  
When he's talking to you a Finnish introvert looks at his feet. A Finnish extrovert looks at yours!

Non-joke, from Living with an Introvert:  Life in the Slow Lane:

Silence to an introvert is what oxygen is to mammals.
