Blasted Typos!

I am astonished at my poor ability to spot typographical errors despite my assiduous exercise of what is pleonastically referred to as 'due diligence.'  I see what I bloody well want to see.  I read the following a good dozen times and failed to see the mistake:

Astinence is no mark of a rounder

which I just now corrected to

Abstinence is no mark of a rounder

which is my response to Jeff Hodges'

Absinthe makes the heart go founder.

But I can't hold a candle to my old friend Monterey Tom, the undisputed master of the typo, as he demonstrates here.
