Here's a tiny tool I like: https://gist.github.com/isomorphisms/9537586

It just prints the first `head` line and then random few rows instead of the top few. For me this is nicer than looking at the top 5 lines every time. I'm peeping at different parts of the table and thus gradually getting acquainted with it.

And Seth Brown wrote a few useful small functions too.
