Funny misreadings of postings

Anybody occasionally completely misread a posting, resulting in a rather “different” interpretation?

In http://boards.straightdope.com/sdmb/showpost.php?p=13486317&postcount=2 for some reason I misread it as “…I’m glad you’re airtight…”. Good think I didn’t post a reply. :smiley:

I did read that as “Good thing”…
