Hi! 
What does “quite a bit” mean in this context?
The Merriam Webster shows that “quite a bit” mean “a considerable amount”. http://www.merriam-webster.com/dictionary/quite%20a%20bit
But, I do not think this definition fits the context below, because T-Bag just only found out that there’s a hole behind the toilet in Michael’s cell and assumed that they are [Michael, John, Sucre and Lincoln] planning to break out of this prison. So ... I guess, in this context, “quite a bit” just means “very few, a little”, right?
(Prison Break - T-Bag came around while Michael was talking his escaping plan with John and Sucre in the yard)
T-Bag: Feeling kind of left out, New York? California? Saint Louis? What are we discussing?
Michael: Talking baseball, actually.
T-Bag: Huh, now that's a subject I just happen to know quite a bit about.
(Then John answered their conversation is over and left with Michael and Sucre)
