After a co-worker accidentally types HTanks instead of Thanks in an email, I came to the reliazation that when we are all typing Thanks, we are really typing in the user ID of Tom Hanks in a typical networked computer (first initial + last name). So, next time you write an email, remember Tom. THanks!
Thanks is also one of those words if you repeat it enough times, it sort of loses its meaning. Try it! (make sure you aren't at work or saying outloud).
